Previously we used to see,if rating predictor predict +90 delta then finally codeforces would give 100+ delta. But now if rating predictor predics +90 delta codeforces are giving +80 delta.I think, codeforces rating calculation have just changed.

Anyone facing the same??

I guess the rating calculation system has changed a little bit because I've observed that when I got around same rank(and rating) in a previous div 2, I got +19 but in the Global Round 16 instead of getting a positive delta(according to cfpredictor) , I got -4

    thats because in div2 rounds , the rating is calculated on the basis of only div2 participants even though the rankings show div1+div2. but in global rounds div1 is also included

      I'm talking on the basis of rankings only for div2. Whereas in the global round the rating increase should be higher as it has both div1 and div2 participants.

Rating predictor is a ratist, won't calculate it for newbies anymore. Anyways enjoy positive delta while you still can.
