I have noticed a few things while laddering in Starcraft 2 that I'd like to talk about. First, for the uninitiated, Starcraft 2 match making tries its best to give you opponents who are on your level based on a hidden stat called "Match Made Ranking" or MMR (I'm not actually sure what the second "M" stands for, but I've always said it "made" so whatever). Your MMR is similar to the Elo system designed to rank chess players.
Here's the wikipedia article on Elo if you are staring blankly at that last sentence. Basically, it's a system that should be able to figure out the odds of a player winning a match. The ideal scenario is to have a 50/50 chance of winning every game, but that's where things get funny.
