[SOLVED] Rating Inflation Problem
By MetB, history, 5 years ago, In English

Sorry, It's time for dumb questions again. From what I see the platform is having a problem of rating inflation. As i know, it's not getting from easy/hard contests, because every contest is a zero-sum game. But on the other hand, every new account contributes 1500 rating. Why don't we make the initial rating 0? For people who are already rated on Codeforces we can easily subtract 1500. Ranks will most probably change, but Codeforces system, I think, will easily adapt (since the rank is not big of a deal) and, what's more, problem authors will not be able to blame rating inflation for their problems being too hard (not that they do complain though). Why is this not a solution?

        Still, I started noticing the pattern. I think they coefficients he talks about there are used to fight inflation, so that "newcomers" (alts) will not change the sum of ratings, Mike Mirzayanov is taking ~10 rating every contest from honest competitors. Which is kinda unfair. So this contest deflation is a consequence, not a reason. And reason is this weird rating bias.

Why 0? The initial rating should be equal to the average rating. I think
