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?
