I'm usually good for one really bad move a game... so be patient. I need to learn to ignore the other player's rating. I always tend to play sloppy when I see an opponent with a low (sub 1300) rating.
Tournament Entry Rating is calculated by the formula (CurrentRating + HighestRating) / 2. The entry rating will never drop to more than 100 points below your Highest Rating.
