I'd like to think that my chess game has gotten better (chess mentor, correspondence chess, tournaments, blitz), yet it seems as if over the past month my rating has ballooned. I use my rating more to show marked improvement versus bragging rights and am curious if the site redid the rating system?
Looks more like a case of your RD being very high when you returned to play in October.
Whoops, I meant my blitz play. Not standard :D
