I have participated in 4 Codeforce rounds up till now, my performances were 1490, 1350, 1150(I flopped), 1350, and my rating was 1195 last I checked. I just logged on today and idk how this happened but my rating is being shown as 1420 and if I use tools to check my performances, it shows 1490, 2100(wthhhh), 1450, 1450. Does anyone know why this is happening? Is it because of the rating changes? but surely they shouldn't change my rating to 1420.
EDIT : THEY FIXED THE ISSUE AND RESET THE INCREASED RATING

this is roleback
cheaters are getting removed from contest, and you are getting fair ratings
and in some of the past contests cheating was sky rocket, so yeah it is normal to get such a jump in your ratings
specially if we consider the fact that most of the cheater were pupil or newbie->specialist
kk thanks! but why would I get a 2100 performance for doing ABC in div2? So many people solved those 3 and I did it pretty slow, hence why I got 1150 perf
div2 are considered diffcult for the majority of the codeforces because majority is newbie and pupils
even if you did slow i can see that you have usen little to no attempts for every problem so it is worthy of that score
also, i dont think that 3 div2 problem in 2 hours is slow for a pupil, i havent seen a pupil doing it normally before, when i was pupil i solved 3 questions in div 2 rarely in first attempt, so your performence was good and deserving
also, can you help me with something "https://www.reddit.com/r/codeforces/comments/1o78pno/need_help_with_assigment/" just fill a form mentioned in this blog this will truly help me a lot!!!
yeah of course, thanks for the answer!
I think this is just a bug. The rating was miscalculated during the recent rollback. In Div. 2, it’s almost impossible to reach a performance of 2100 by solving only three problems.
It's definitely a bug.
please tell me its true man, this feels horrible fr
it have never happened before on codeforces
and it is very unliely that such a bug happened only to a 1 profile
not impossible though
It happened 100 times before
bro, this happened to 50% of people, not one profile
On discord, someone suggested that since it was my second contest, my rating was adjusting and I got +230, and while doing rating rollbacks Codeforces thought that my +230 meant that I must have got a really good performance
Anyways i'm happy my rating isn't VERY HIGH now, I'd prefer it reflect my true rating, which I believe is around here or a little bit lower maybe
btw just in 10 days you have managed to achieve such a rating!!!
have you already been in a competitive programming platform??
I used to do programming before, and then I did problems for my national informatics olympiad, and just random problems. Eventually I went on Leetcode for a little bit but switched to Codeforces fairly quickly, so I already do have a little experience with CP
I have +200 ratings to.. Kinda dramatic I spend several years, dreaming about 1400, after about 1600 and at result get expert without contest..., so I can't create "Finally Expert" blog/// ^__^
I think you're trying to say something to me, huh? :)
no
finally expert isnt created by you only, it is a cf trend done by a lot of context, so it is highly unlikely that she/he will do it referring you
I know that "Finally Expert" wasn’t created by me I’m just trying to be funny so don’t take it too seriously.
chill bro im taking it funny too
i was just trying to be paragraph guy
I highly suspect that the rating has been recalculated without considering deduction of displayed rating for users' first contests.
For example, the writer of this blog got $$$+565$$$ on their second contest, but if you check carrot on https://mirror.codeforces.com/contest/2145/standings/participant/220903086#p220903086 this page, their performance is only $$$1347$$$ (which looks quite accurate compared to other past contests). Considering that they got $$$+521$$$ on their first contest, their real rating should only be $$$1421$$$, so their real rating should decrease after the second contest, which means its delta should be less than $$$350$$$ after applying the "bonus". If we assume that their rating was really calculated based on their displayed rating ($$$521$$$), then getting $$$+215$$$ (plus $$$+350$$$ bonus) is quite reasonable.
my final rating is kinda similar (~+60) but i reached CM in between but the rating gains i got are too high i feel? is this a bug
I reached specialist too for no reason
It's definitely a bug
if cheaters are getting flagged and removed.. there must not be much difference in between the contest rating and new updated rating. but today when i checked my last ratings where i actually got a good increment was reduced. One of my newbie friend just became pupil with 1204 of rating and now we checked he's rating was down by 55 pts.
