I want to understand how rank 4 of July lunchtime div2, got +314 which got him to 2251 from 1937. But the rank 5 got only +42 even though his initial rating was lesser.
Both profile links:
Rank4
Rank5
You can check out the rank list for even more bizarre rating updates.
The rating system changed today. Sadly they decided to make the change as hidden as possible. Everyone had their past contests recalculated and currently everyone has 2 different ratings. The public one (Code Chef rating) and an hidden one (the new Elo-MMR rating).
Since today, only your Elo-MMR rating will update. And since this is a different rating, it is very likely it was different than your old rating. Your public rating will converge to the Elo-MMR rating within a few contests.
In the near future, everyone’s old rating will be set to the Elo-MMR rating. Why it was not done already I don’t know.
elaborate about what exactly? I don’t know the details either.
I guess ratings are calculated to first 4 users
It is not hidden, if you do want to look for it.
Thanks for replying, so as I understand, the new rating system benefitted rank 4 because it was a new account ?? right?
So its just easier to create a new account and then push for 5 star instead of grinding it on an old account?
It all depends but this can happen, yes.
