I greatly enjoy CC, in fact I love it, and it’s helped me improve quite a bit. However, I’m pretty much ignoring ratings for a while, as they are pretty erratic. Some easy problems have a high rating and some rather tough ones have a low rating. So my own problem rating surely doesn’t express my (lack of) skill.
That’s probably because the ratings are far from reaching anything near steady-state. Some of these problems have had only two or three attempts— hardly enough to settle down to a realistic rating. Obviously the K factor (or whatever it’s called in the Glicko method) is high.
I guess the best solution is to attract a few thousand more players to the site and give the problems a real workout!
