Re: Ask Graeme?
I'll post something inside you.
Re: Ask Graeme?
I can confirm that the buzzers are activated once Nick presses the button to start the clock. This means you can buzz whenever the clock is going (so in any round), but not when the clock isnt going.
Whilst waiting to play our final, Conor and I asked the floor manager (Jay) about this, and he started the clock for us and let us mess around with the buzzers. It was great fun.

The letter distribution has changed quite a few times over the years. To start with, let's look at series 66 only.Chris Marshall wrote:Is it possible to get a letter distribution frequency for each letter over the data you have?

The vowel pile is a bit more tricky, as we don't have any known data points to work with, only their frequencies relative to each other. We do know that there have to be at least 55 vowels in the pile at the start of the game (in case both contestants are Jonathan Rawlinson), but without an exact count it's difficult to reach details of the actual distribution. So it's much more finger-in-the-air.
My rough guess, based on trying numbers and seeing if they give counts roughly near whole numbers, are that as of series 66 there were about 15 As, 20 Es, 13 Is, 13 Os and 7 Us.
Re: Ask Graeme?
Remember the Gotcha where 'Richard Max' buzzed in on one of later rounds claiming he thought it was the conundrum... I'm surprised to learn that could actually happen. What's to stop someone buzzing in half-way through for any reason ("I can only find four letter words, can we start again?" or "I'm going to be sick!" for instance)?JackHurst wrote:I can confirm that the buzzers are activated once Nick presses the button to start the clock.

Re: Ask Graeme?
As a cross-check, I tried finding the maximum number of times each letter was seen in a game in series 66. Gratifyingly, the answers for consonants were identical to Graeme's which suggests stability in the pack if nothing else.
For vowels I get answers that are slightly lower, which I think makes intuitive sense. Taken at face value, our numbers imply that there were never fewer than 3 As, 3 Es, 2 Is, plus a single O and U left in the pack at the end of a game.
The one concern I have with Graeme's numbers is the suggestion that there were 2 Ks in series 51 and 52. In the 15-round era we have only seen 2 Ks 8 times, 5 during a 2-week period in series 46, and the other 3 in a single week in series 49. If there were 2 Ks available for a prolonged period at any other time I think it's stretching credibility to suggest they wouldn't both have been seen in most of the games during that period.

Re: Ask Graeme?
True. I've had a look at series 51 and 52 and I don't see any evidence that there was more than one K. However, the frequency of K for those two series was still significantly greater than the frequency of Q, X, Z and J.Clive Brooker wrote:The one concern I have with Graeme's numbers is the suggestion that there were 2 Ks in series 51 and 52.

Is there a link between some of the great players playing in final stages to the distribution of 'nice' letters for the production to ensure big scores for pulicity purposes?

Re: Ask Graeme?
Great work both but I really don't think there are that many U's. I'd say six at the most, possibly even five. How many games in Series 66 saw more than five U's appear?

Re: Ask Graeme?
Maybe ten years ago there was a suggestion that for a couple of months one of the letters (possibly J) never appeared once, suggesting it had been mislaid. Is this true, and if so was the length of absence statistically significant?
What evidence is there that letters are manually sorted, rather than shuffled?

I remember the thing about the Js. With the vowels you could look at how the probability of each vowel changes depending on what has come up already to work out actual numbers.

Re: Ask Graeme?
How many times has the same target come up in two consecutive numbers rounds? And in any of those instances, has it been possible to solve the rounds with exactly the same solutions twice in a row? (e.g. 100 6 1 8 3 2 -> 801 and 100 50 75 25 1 8 -> 801 could both be solved with 100x8+1)
I'm not dead yet. In a rut right now because of stress from work. I'll be back later in S89. I also plan to bring back the Mastergram - if I can find a way to run a timer or clock through pure MediaWiki without having to upload to Vimeo every time.

Sorry I can't do pretty results tables like Graeme can.
I can't do probability either, but looking at the bulge at 3 and 4 in the "all series" numbers I think Jack is right; there must have been long periods where there were no more than 5 Us.

Re: Ask Graeme?
I know it's often been pointed out that we don't seem to get enough triple or quadruple vowels in individual rounds. No doubt that can be tested with the data now available. However, conclusive evidence is more easily found: between games 3636 in series 51 and 3780 in series 52 there seems to have been a policy whereby either the J and the Z or the Q and the X were excluded (or put at the bottom of the pack) on alternate days.David Williams wrote:What evidence is there that letters are manually sorted, rather than shuffled?

A quick question that occurred to me last night (I've only just rediscovered the Post-it note with it scribbled down on):
Susie Dent's contribution to Countdown history has been acknowledged via the conundrums SUSISDENT and SUSIEDANT. But given her nine letter name, made of up a valid selection of common letters, has a letters round ever produced a perfect scramble of SUSIEDENT?

Re: Ask Graeme?
In relation to letter frequency's, the Spreading the Word book states that there are 66 consonants and 65 vowels. However, that is from 2001 and as we know, the amounts have changed, but not by that much it seems. Having 66 consonants makes sense as the maximum number of consonants that could be picked in a game is 66, if 6 consonants were picked in all 11 letters rounds. But seen as that never happens and they'll be 10 letters games from now on, there isn't a need for 66 consonants or 65 vowels, but I suppose if you have more than enough letters you have more letter variation from game to game and a greater variety of words to be found.
I'm sure there have been a few episodes with two K's as people above have said. I remember seeing it. I personally think there should be two K's, as there are words like: kayak, karaoke, khaki, knack, knapsack, knock, kook, knickers, knuckle, trekked, trekker, trekking, kick, kink, kiosk... that you can never get on Countdown with one K. I know it would be rare to get two K's in one round but at least there would be the possibility. The Gotcha episode appears to be the only episode with two K's in the same round, but admitedly the letters were put in a specific order for that episode.
I remember for a few weeks in around 2010, there were two Q's appearing per episode (thankfully not in the same round). I suppose this was to increase the likehood of getting a round with both a Q and U. The better way is having more U's, which is less daunting. It seems there are currently 6 U's, which is better than in a long period from around 2007 to 2009ish, when there seemed to be only four U's, one V, W and Y which decreased the amount of possible words. I remember that the only time there was more than one W per game was when the M was the wrong way around. As Graeme said, it seems from S62 (2010) onwards, they sneaked some of those letters back.
I also think there should be two Z's (as off-putting as that may be) because of the wealth of double Z words: blizzard, buzz, buzzard, dazzle, dizzy, drizzle, fizz, fizzle, fozzy, frazzle, frizzle, fuzz, gizzard, grizzly, huzzah, jazz, jazzy, lizzy, mezzo, muzzle, nozzle, palazzo, piazza, pizza, pizzicato, puzzle, quizzical, tizzy, twizzler... Such words are currently impossible to get. It is ironic that you can't get the words 'puzzle' and 'quizzical' on Countdown.
I know Scrabble and Words With Friends have only one K and one Z, but you can use a blank square to make an extra one. At least the 8 and 9-letter words which have either two K's or two Z's can be used as TTT's and Conundrums respectively.
There was an article on the BBC News wesbite recently saying that the letter values in Scrabble should be changed to reflect the changes of letter-use from the days when Scrabble was first invented, 80 years ago. http://www.bbc.co.uk/news/magazine-20984707

Re: Ask Graeme?
How do you reckon previous octochamps' totals in the classic 15 rounder format convert into the new 10-letter, 4-number 15 rounder format? Much difference? Maybe a few points a game on average? This will be interesting to see over the next few series

Re: Ask Graeme?
Although I'm not Graeme, I think when scores were converted from the 9-round games to the 15-round games, a score of about 61 was equivalent to 100. So proportionally more numbers (and conundrums for that matter) seemed to lead to higher scores, but not by much.Andy Platt wrote:How do you reckon previous octochamps' totals in the classic 15 rounder format convert into the new 10-letter, 4-number 15 rounder format?

Re: Ask Graeme?
Now here's one to create a debate.
A numbers game replacing a letters game, which of course means a lot of the time, 10 points. This, as opposed to whatever you might get with the letters. Now considering MOST of the time you wouldn't get a nine letter word, you could say on that basis the score ratio would increase, but against a record score of 146, where nines are inevitable? This could run and run, but to me I think it could just increase some scores ever so slightly.

Re: Ask Graeme?
Yeah, I'd say it would increase average scores, but decrease the chances of a 146 or 146-beater. However, 146 can be beaten with three 9s, so essentially there's only a 3/11 chance that by reducing the letters rounds to 10 you'd actually take away one of your nines. So the extra numbers could still boost your score even in this case.

Yeah probably consistently higher scores but less fluctuation/standard deviation so 146 maybe becomes slightly more elusive. I'll do a case study later maybe

Re: Ask Graeme?
Graeme, not sure how hard this would be to do but could you make a list of all players who've had at least one 13+ max game, and their amounts of 15, 14 and 13 max games?
So Conor and Kirk (I think) would be:

Re: Ask Graeme?
Surprisingly it appears that the change to 10/4/1 actually increases the chance of a 146+ max being available.Gavin Chipper wrote:Yeah, I'd say it would increase average scores, but decrease the chances of a 146 or 146-beater. However, 146 can be beaten with three 9s, so essentially there's only a 3/11 chance that by reducing the letters rounds to 10 you'd actually take away one of your nines. So the extra numbers could still boost your score even in this case.
Using Graeme's letters round max distribution and assuming 1 large/2 large numbers picks (i.e. 98% chance 10 max, 2% chance 7 max) the chance of 146+ being available is increased from 2.14% to 2.89%
This can probably be explained by the increase in the chance that 2 available 9 letter words are enough to get you to a 146 max.
I'd also like to take the chance to thank Graeme for his great work on this thread, a delight to any stats-geek.

Yes. No game besides that one had eight or more five-vowel letters rounds, although this one had seven.Conor wrote:I suspect Series 68 might break the record.

In 15 rounders, both contestants scored the maximum numbers round points available in 170 out of 2596 games, which is about 6.5%. Both contestants scored 30/30 on numbers in 154 games, or 5.9%.Gavin Chipper wrote:In what proportion of games (separately for 9 and 15 rounders) are all the numbers games rendered "worthless", by both contestants maxing them all? Actually I know you can only go by points rather than true maxes so yo uwon't be able to get whether a 7 is the true max. So maybe two separate stats - one for all max scores (erring on the side of inclusivity), and one for all 10s (erring on the side of exclusivity).
In 9 rounders, both contestants scored the maximum numbers round points available in 401 out of 2944 games, or 13.6%. Both contestants scored 20/20 on numbers in 387 games, which is 13.1%. Note that while the database knows about 3035 9-rounders, I've excluded those where we don't know the max.
Re: Ask Graeme?
Speaking of numbers of vowels, has it always been an official rule that you had to pick between 3 and 5 vowels? Was it ever mentioned on-screen, as nobody (other than contestants) seemed to be aware of it. Also, are there any anomalies - I'm positive I remember a 2-vowel letters round slipping through in the last few years.
Re: Ask Graeme?
Nope, wasn't always a rule. Not only did Andy Cusworth pick 6 vowels every time against Shacklady, in round 1 he picked the 6 vowels straight off the bat.

Re: Ask Graeme?
In a related theme, in the guidelines I noticed that it said (and I wish I had the exact words in front of me, but I don't) that a failure to conform to these rules (and I remember they are official rules), would result in the round being scrapped and the contestant having to pick them all again.
Now seen as though I almost always go CCCC to start every round, what if I got the consonants QZJW, and decided "hey, you know what, I don't really fancy this" and just kept picking consonants? I never really asked Jay or Damian or anyone about it, nor did I consider doing it when I filmed, but the guidelines do leave the exploitation open and it would be interesting to see what the production team would do about it. Presumably they'd just stick the same bad consonants at the top again, rendering the exploitation fruitless, and give you a warning? Still probably worth a try!

Re: Ask Graeme?
Ha, mental stuff. Are there any other anomalous rounds other than the 2-vowel round I mentioned (anyone find that?) since the rule was introduced? I'm sure it was brought up and Damian said they spotted it, but allowed the round to continue because it was a decent selection anyway.Conor wrote:Nope, wasn't always a rule.

Likely that once you'd got CCCCCC and asked for another C, Rachel would tell you that you need 3 vowels now, so the first 6 letters, however bad, wouldn't change. We'd just resume the recording with you picking your 7th letter as a vowel.Andy Platt wrote:Presumably they'd just stick the same bad consonants at the top again, rendering the exploitation fruitless, and give you a warning?

I don't think they necessarily always do a retake.

Here's a table of average max letters scores by episode type, for all 15-rounders. Only letters rounds are counted, in order to eliminate any variation caused by finalists opting for more challenging numbers picks.

A note on the limitations of what this analysis can tell us: if the production team were to deliberately arrange the letters for a high max in just one or two games ever (and I should stress that I've never seen any evidence to suggest this has happened), this table wouldn't show it up. Short of catching someone in the act of messing about with the letters, I don't think you could ever know, as it could be explainable by chance. However, if they routinely did it for certain classes of game as the question suggests, it would show up, and it doesn't.
The one outlier in all this is the final of the 30th birthday championship, with its three nines and letters max of 109. Since the sample size is 1, this isn't evidence of anything untoward. Of the 2,596 15-round games in the database, 69 of them had 109 or more points available from letters. This is about 1 in 38. So if anyone thinks the 30th birthday championship final is evidence of deliberate manipulation of the pack, that's roughly equivalent to rolling two dice once, getting two sixes, then claiming that's evidence the dice are loaded.
So there'll be no need for the tinfoil hats today.

Re: Ask Graeme?
No letter has been unseen for more consecutive rounds than J. It appeared in the series 46 final on Christmas Day 2001. Two months, 44 games and 480 rounds then passed with no J before it was seen again on 25th February 2002.David Williams wrote:Maybe ten years ago there was a suggestion that for a couple of months one of the letters (possibly J) never appeared once, suggesting it had been mislaid. Is this true, and if so was the length of absence statistically significant?
Other notable lengths of absence:
In series 61 on 30th October 2009, a V was selected in round 1. That was the last time we saw the V until the start of series 62 in January 2010. It had been unseen for 396 letters rounds.
The next appearance of the X after round 5 on 23rd May 1988 was in round 6 on 24th August of the same year, an absence of 398 letters rounds.
In all 2596 15 rounders, the J has been unseen in 711 of those games, the X in 617, and the V in 367. So if we take this as an indicator of how probable the absence of a letter is, the probability of a given 44 consecutive games in those 2596 having no J is (711/2596)^44, which is about 1 in 5.6 * 10^24. There were 2596 - 44 + 1 = 2553 opportunities for it to happen in that time, but that doesn't even make a dent in that number. It's the same story with the absences of the X and the V, so we can safely say that, whether it was by accident or design, those letters were removed from the pack.
Incidentally, this game surprisingly had no Ls in it, and is the only such 15-rounder.
We've seen that there's no evidence that the letters are deliberately arranged to produce longer words or higher scores. However, it's a certainty that the order of the vowel pile is not entirely random. It gets tinkered with to remove consecutive occurrences of the same letter.David Williams wrote:What evidence is there that letters are manually sorted, rather than shuffled?
I've run a simulation of 10,000 random shuffles of the vowel pile, using the distribution I guessed at earlier, and then truncated the length of each shuffle at 40, because that's the average number of vowels we see in a 15-round game. I've used this as the basis for estimating probabilities.
In these 10,000 shuffles, a run of three consecutive Es happened 5,611 times, which means you'd expect this to happen roughly every other game. On the show, it hasn't happened since 2010. Three consecutive As should happen approximately once every four games, and that hasn't happened since 2011.
According to the simulation, two consecutive As should appear in 84% of 15 rounders, but the same figure on the show is only 14%. Two consecutive Es should appear in 98% of 15 rounders, but on the show it's only happened in 28% of games.
Presumably, the reason they make an effort to remove clusters of identical letters is that if five vowels in a row turn out to be E, which is not as unlikely as you might expect (it should happen in about 1 in 20 games), the production team would get letters from people who don't understand probability complaining that "you're not shuffling the letters properly".
I'm told apterous does the same thing. This is perhaps why we're surprised at CO-events when the Countdown board game turns up selections like TPGLEEEEE - that's just what true randomness sometimes looks like.

As you can see, "big" matches do not, in general, have favourable letters compared with ordinary series games (episode type P). So I see no evidence that the letters are, or have ever been, deliberately arranged to give high maxes. If anything, with the exception of CQF (CoC quarter-finals), the average max for the higher-profile games is lower than in ordinary series games. Not sure why. Also not sure if the difference is even statistically significant. I'm sure there are equations that can help with this, but I'm not Michael Wallace so I don't really know what I'm doing.Code: Select all

Re: Ask Graeme?
Okay, we once 'lost' the J and V for a few months. This was , i think, because we had conundrums with J and V in, so we needed 2 of each letter, one for the reveal, one for the solution. I seem to recall that there was a shortage of such letters, so we pinched J and V from the normal letters piles to compile the conundrums, and they were not put back afterwards.
Beyond that, everything is shuffled like a pack of cards, nothing is ever messed with, we get what we get.

On a semi-related note, what are the average margins of victory in each individual finals match? (i.e.: On average, by how many points does the #1 seed beat the #8 seed in the first quarter final? For series in which the #8 seed won the first QF, this value would be negative; for instance, Phil Watson beat Steve Briers 83 - 73, so you'd use -10.)James Robinson wrote:The answer is 6: Series 5 (John Wallace), Series 21 (Lew Schwarz), Series 24 (Norman Christian), Series 30 (Graham Cross), Series 44 (Kevin McMahon) & Series 55 (Steven Briers).Giles wrote:In how many series has the number 1 seed lost the quarter-final against the number 8 seed?

Re: Ask Graeme?
As I said a bit further up, there was a run of almost 150 games not so long ago when either the Q and the X or the J and the Z turned up on alternate days (occasionally one of the pair would fail to reach the top of the pile). That didn't happen by chance.James Robinson wrote:There is certainly a precedent, because in my very first game 10 years ago, me and my opponent were informed before the game started that the J and Q had been removed, and lo and behold, they didn't turn up.Countdown Team wrote:Beyond that, everything is shuffled like a pack of cards, nothing is ever messed with, we get what we get.
Does anyone remember that during COC13 (the first games with Jeff and Rachel) we all noticed immediately that the "shuffling" seemed different. This was swiftly confirmed by Kate Horton (and denied by Mr Team). Would that set of games (165 letters rounds) provide enough data to test whether the observed letters sequence corresponded more closely to random selection than it has in the rest of Countdown history?

Yes, it was quite striking at the time how often we got pairs (or triples) of the same vowel coming out. I liked it and theoretically it opened up some new areas of the dictionary. I seem to remember that most of the top players disliked it as it would tend to bring down maxes.Clive Brooker wrote:

Re: Ask Graeme?
The distribution of letters has been tweaked over the years. If someone decided that even one Q in the pack over-represents its frequency in the language and there should effectively be "half a Q" in the pack, that's how you'd do it. The only alternative would be to double the frequencies of all the other letters, and then you'd find they don't all fit in the consonant box.Clive Brooker wrote:As I said a bit further up, there was a run of almost 150 games not so long ago when either the Q and the X or the J and the Z turned up on alternate days (occasionally one of the pair would fail to reach the top of the pile). That didn't happen by chance.James Robinson wrote:There is certainly a precedent, because in my very first game 10 years ago, me and my opponent were informed before the game started that the J and Q had been removed, and lo and behold, they didn't turn up.Countdown Team wrote:Beyond that, everything is shuffled like a pack of cards, nothing is ever messed with, we get what we get.
We can infer what the vowel and consonant piles looked like at the start of every game for which we have round details, as far into the pile as the number of each category we see. This isn't 100% infallible, as very occasionally they have reason to give up halfway through a round and throw the letters away, but this sort of thing is rare enough that it shouldn't matter. Anyway, the point is that having inferred what the vowel pile looked like at the start of the game (or at least the first N letters, where N is the number of vowels that came out in that game), we can look through it for clusters of identical letters.Clive Brooker wrote:Does anyone remember that during COC13 (the first games with Jeff and Rachel) we all noticed immediately that the "shuffling" seemed different.

The shuffling system does indeed appear to have been different during COC13. Here's a table of how often the vowel pile has been known to contain a cluster of three of the same letter in all 2,596 15-round games, and how many of those were in the 15 games of CoC13. (The vowel pile has never contained UUU in a 15 rounder.)

AAA 10 4
EEE 30 5
III 5 4
OOO 7 3
I'm sure you know this anyway, but for the avoidance of doubt, if anything I'm coming up with in this thread sounds like a dig at you or the show, it isn't. I'll repeat that I'm not suggesting any impropriety or any deliberate attempt to manipulate what words come out - in fact we've already seen that any suggestion of that kind is rubbish.Countdown Team wrote:Okay, we once 'lost' the J and V for a few months. This was , i think, because we had conundrums with J and V in, so we needed 2 of each letter, one for the reveal, one for the solution. I seem to recall that there was a shortage of such letters, so we pinched J and V from the normal letters piles to compile the conundrums, and they were not put back afterwards.
Beyond that, everything is shuffled like a pack of cards, nothing is ever messed with, we get what we get.
Nevertheless, if someone asks what evidence there is that the ordering of the letter tiles has a non-random element to it, and I have a look and find that three consecutive Es has only happened 30 times over the past eleven years when truly random shuffling should make it happen every other game, it's interesting. That's why I assumed that the vowel pile, after shuffling, is manually examined and re-sorted to remove consecutive occurrences of the same letter. I'm not saying there's necessarily anything wrong with that, or even that it really matters at all, and if I'm wrong in assuming this happens then accept my apologies for suggesting it. Even so, it's indisputable that there's something about the shuffling process, conscious or otherwise, that makes clusters of identical letters much, much less likely than would be expected by chance. (Whether anyone should care is more open to debate.) If the letters are shuffled face up, that could explain it. Humans can't consciously generate truly random sequences, mainly because repeated occurrences of the same thing don't look "random" enough to us.

Re: Ask Graeme?
On the subject of shuffling face-up - What - Statistically are the chances of getting THREE available nine letter max rounds in a row?
How often has this happened and has there ever been more?

Re: Ask Graeme?
I couldn't even begin to work out what the exact probability is, but three consecutive letters rounds in the same game having a nine available has happened six times. There have never been four or more consecutive rounds with nines available.Dave Preece wrote:On the subject of shuffling face-up - What - Statistically are the chances of getting THREE available nine letter max rounds in a row?

Rounds 2-4 in episode 3967
Rounds 9, 11 and 12 in episode 4607
Rounds 1-3 in episode 4842
Rounds 7-9 in episode 5227
Rounds 3, 4 and 6 in episode 5434
Rounds 3, 4 and 6 in the 30th birthday championship final - this was the first time all three nines were spotted.

Putting these two together makes me wonder if they couldn't find the Ls for the conundrum letters in this episode, so they had to pinch 4 of them from the letters pack.Countdown Team wrote:Okay, we once 'lost' the J and V for a few months.
