On a more serious note, the rating system on Codeforces still has major issues. The top ratings continue to inflate heavily, and if anything it seems that volatility has only increased (subscriber gained almost 200 points for winning yesterday's contest when previous round-winners near the top ten would earn less than 100. Would tourist just lose 300+ points for another performance like his last? :P). Why was the system changed so significantly? Are these the results that we expected to see?
