Hello Everyone,
Are the seeds for the contests on CF-Predictor calculated correctly?
On a recent contest: many users (such as me) ended up getting negative delta even though we got a lower rank than our seed (meaning we did better than "expected"), which is contradictory.
Does CF-Predictor calculate the seeds based on registered participants and not those who actually took the contest (thus making it a bit inaccurate) or are rating changes a bit off for codeforces?
Auto comment: topic has been updated by vkgainz (previous revision, new revision, compare).
The avg delta in div1 is -12. The avg delta is div2 is +40(This includes new accounts).
the average delta in div2 is still negative overall (it was also around -10 last time I checked), it is just because of the initial rating gains that make it look positive.
Oh wow, didn't know that. Did you find this out by looking at past data or was there a post somewhere? As far as I know the last rating explanation post was made like 5 years ago.
Just run this and input contestID
