From a rough eyeball estimate, it seems that games have a half-life around 100 days

:joy:
The radioactive decay comes back.
We already tried that to estimate the end of the first round

Looks like the exponential decay worked pretty well down to ~20 games last time, which is pretty reasonable. Too early to tell if it’ll work as well this time, but we’ll see

Yes. the first round had a slope on the log graph fairly constant for the first 300 to 400 days, flattening out slightly until around 1000 to 1100 days, at which point it clearly steepens. Cleary the second round initial days were dominated by mass timeouts. but does seem to be also flattening some now. I could theorize the final “acceleration” could be due to endgame generally played faster, and final games having some psychological pressure (the needs of the many outweighing the needs of the few or one)

For those of you who are fans of powers of two, there are now fewer than 256 games remaining to complete in round 2… so for half life estimate, still 800 days to go

After the Maya calendar, the Gregorian calendar, I propose we get the Lys calendar.

Hopefully will end (and win :grin:) my last ongoing game before those 800 days. Already impressed by being in the last 5%.

Thanks @Lys - because I’d be interested to see how fast games get finished in this 2nd round compared to the 1st round. … And if it’s not asking too much, both a “games completed (in any manner” vs. time and a breakdown comparison of how many finished by 1) “full play, passing, and counting”, 2) by a player resigning, and 3) by “time out” - that would be interesting to me.
