Originally posted by KewpieI remember when the chap listed below disappeared a few of us wondered why ( I'm in same clan ), his ratings obviously plummeted given the astronomical rate he'd attained...he had hundreds of games ongoing and I note that your game with him was one of the first to time out, hence the full 12-1300 points difference would 'supposedly' be observed when making any calculation.
There's a useful rating chart in Thread 80000 as well.
The crux; you were robbed of a few points lol !!

He was rated 2316 when I timed him out, so I got the maximum possible 32 points for the win. And of course I lost zero points in the other game where he naturally demolished me! 😀

Originally posted by KewpieI had no idea about the 'graph accuracy'...it just seemed somewhat odd in that he 'apparently' lost 24pts whilst you gained 32. It's got me curious as to that accuracy element, I can't find anything published as to why and how...
I went from 1079 to 1111, according to my graph, that's 32. His graph shows a drop of 24 points, certainly, but remember that rating chart is only accurate up to 2100 or thereabouts.

New Rating= Old Rating+K*(Score- win Expectancy)
K is a constant,32 for 0-2099, 24 for 2100-2399 and 16 for 2400 and above. In other words when you reach 2100 each game has less effect on your rating and it drops again when you reach 2400.
