Tjoex won a game, but it was an unexpected victory
Huh? Is a 1651 rated(not trueskill mean) player not expected to beat a player with a rating of 529? I get that this rating doesn't 100% accurately represent their trueskill rating, but surely Tjoex should be expected to win the game by the system?
Just to clarify: I like this system, and I'm not surprised Tjoex shown rating went down from him winning a game against a much lower rated player, but I would think that would be because his standard deviation increased due to his opponent being an outlier in the skill level he usually plays against, not because he isn't expected to win the game?
