601 place with 1333 gets +375, but worse with -89 and 469 place gets only +319... Hm..
Codeforces rating system don't like me. It hurt to realize it :(
worse had 469th place (higher than some top breakthroughs), he definitely had lower rating than them, but he got less rating points. It seems quite a strange.
DmitriyH, didn't you have an idea to find pairs of participants A, B that startRatingA < startRatingB, placeA < placeB and deltaA < deltaB?. Is it common situation?
One possible explanation could be that worse's rating is more or less determined to be at that range (let's say 0 +/- 350) while for the other people the margin of error in their determined ratings could be higher (let's say 1333 +/- 450).
It would be interesting to also include matchesA < matchesB (possibly implying a larger margin of error in determining their ratings).
Yeah, it could be right, but page about rating doesn't mention anything like that (any input except old ratings and places) :(
Yes, on CF the rating is primarily based on Elo, which does not take that into account unlike on sites like Topcoder, where we can see volatility.
Isn't this a higher breakthrough?
i think DmitriyH doesn't include unrated users in his Top breakthroughs.
you and illi are so annoying! and you're first by contribution only because of your useless stats
Its fun, maybe you dont like them, but many others do
Different results in best hackers between you and illi why is that?
Your link is about other round. This has the same results.
My mistake, sorry
