My peak rating on Codeforces was 1142 and 1116 was my current rating. It was fine a few days ago but today when i saw my rating i was surprised. My peak rating decreased to 1128 and my current rating decreased to 1089. I don't have any proof like a screenshot or something but i am very very sure that it was 1142(peak) and 1116(current).
Also i haven't received any notices or mail from codeforces about this. My ratings just changed magically. All of my submissions are fine and i think ranks are also fine but my ratings changed.
What is this MikeMirzayanov ? Please fix this @MikeMirzayanov.
Rating rollbacks, I went down from 1484 to 1479 :/
Occasionally, there is a yellow thing at the top of the screen that says "Previous rounds ratings will be recalculated" or something like that, which can change your recent round ratings.
Where is this yellow thing is shown? on the contest page ?
No, when the ratings are back, the yellow thing disappears. But when you notice contests disappeared from your rated history of contests, there should be the yellow thing.
It's called an "announcement" lol
Happened with me also. They recalculate ratings sometimes (eliminating cheaters)
