After an octorun is completed and we get two new contestants, it always seems to be that the one sitting in the champion's chair loses the game.

Obviously, it doesn't "always" happen, but is my hunch broadly correct? Why wouldn't it be roughly 50-50? Or is it?

When they have two new contestants I think they use a reserve player (who likely just missed out on passing the audition) who normally lives locally. Maybe they're put in the champion's chair?

25 returning contestants in Series 92 now. Are they running out of contestants?

Dylan Taylor is the record holder, having scored in all 60 of the numbers rounds he played.

With the small numbers, because there's few enough of them, it would be enough to just see the frequencies of each one. With the generator a more sophisticated statistical technique may be required. But you could just separate the targets into blocks of 20 or 50 or whatever to check each block is equally represented within reason.

I've never seen any evidence that the random number generator isn't sufficiently random, except for that brief period in 2017-18 when Sam Prouse noticed it was repeating a previously-seen sequence. I'm not really sure how you'd test if its distribution was within the limits of what you'd call "truly random".

Doesn't look like there's anything dodgy going on with the selected numbers, either.

I don't have any way to search for this systematically, but here's one example: Nick Deller in series 28 with CROISSANT.

Martin Hurst wrote: ↑Thu Apr 10, 2025 9:10 pm How many episodes have there been that have pitted two contestants both with verbs as surnames against each other?

Not searchable, I'm afraid. I don't have a big list of all verbs.

That, combined with his 6 small games, is an insane demonstration of mental athleticism and cognitive function in competition.

He maxed 56 of them as well, and in the other 4 he was one away. Only 12 points dropped!

Philip A wrote: ↑Fri Apr 11, 2025 11:21 am It makes me raise another question: which regular series has the lowest percentage of conundrums solved, barring tie-breaks? What about longest run of unsolved conundrums barring tie-breaks?

In more recent years, Series 19 has the lowest percentage of non-tiebreak conundrums solved. Only 35 out of its 66 conundrums (53%) are known to have been solved.

In more recent years, Series 75 came close - 60 of its 109 conundrums (55%) were solved.

At the other end of the scale, Series 48 had 95/110 conundrums solved (86%).

Series 7 shows up as only 36% solved, but there are so many details missing for that series that I've disregarded it.

The other question was already answered in March.

Philip A wrote: ↑Mon Jun 09, 2025 8:56 pm In terms of percentages, how many episodes of Series 90 featured a returning contestant? How does this percentage compare to Series 91?

These figures may be inaccurate, because the process for determining whether, say, "Terence Newnham" and "Terry Newnham" are the same person isn't perfect. The Terence/Terry case I spotted myself and fixed the database so he was included, but I may have missed some others.

Series 90: 49 out of 118 episodes (41.5%) featured a returning contestant, including all seven finals matches.
Series 91: 24 out of 125 episodes (19.2%) featured a returning contestant, which included only one quarter-finalist (Christine Smith).

Series 92 saw many high-performing returners. 81 out of 125 episodes (64.8%) featured a returning contestant, including all seven finals matches.

That last stat - not sure that’s good tbh. I posted numerous stats about S92 returnees elsewhere too.

Think we do need more new contestants.

How many rounds have had 2 or 6 vowels (and indeed other non-standard numbers (0, 1, 7, 8, 9) if these values exist)?
How many of these instances have slipped through since 1995 (and the 3V 4C rule)?
If a manageable number, could these please be listed?

All time, for rounds where we have the necessary details:

1 vowel: 5
2 vowels: 218
3 vowels: 33144
4 vowels: 41525
5 vowels: 2635
6 vowels: 9

Two of the 1-vowel selections were in Episode 574 (Matthew Francis would have picked both those rounds). Another two 1-vowel selections were in Episode 650 (both Philip Hardingham). The other 1-vowel selection was in the Masters episode M84 (I'm not sure what the picking order was for these episodes).

From Series 30 (3rd July 1995) onwards:

1 vowel: 0
2 vowels: 13 (Edit: turns out this includes the Noel's House Party Gotcha episode, so 12 "real" rounds)
3 vowels: 27195
4 vowels: 37835
5 vowels: 2472
6 vowels: 1 (R13 in episode 8536)

I'm surprised by the 3 v 4 vowel stats. My impression is that while Apterites pick 4 vowels, pretty much everyone else picks 3 most of the time.

Great work as always.

Has any contestant ever chosen 3/4/5 vowels and 6 small, 1/2/3/4 large at least once? In other words, has any contestant chosen every selection possible?

I did- though that's including the finals. Didn't want to have a regular selection- so mixed it up in the hope that it would make me more unpredictable to play against.

I probably should have asked how many contestants. But yes, finals and Champion of Champions all count as well as prelims.

I always love a Graeme update in this thread.

According to Mike Brown's notes, the culprit is Gary Franks, as "DW chooses numbers". I believe - although I have no way of confirming this - that Legs 1 and 3 would be C1 Letters, C2 Numbers, and vice versa for Legs 2 and 4, and the current leader chose whether to pick Letters or Numbers in the 5th Leg.

Has any contestant had the same 9 letter word appear more than once in their games? And did they spot it?

RELATIONS. Didn't go for an exciting variant.

How many octochamps did not score a century in any of their preliminary matches?
