Ohh yes there is Brian. Read up on the fargo ratings system. The handicap is dynamic. You don't get an established handicap until you have lots of play under your belt and your score starts to stabilize. So a new person sneaking in plays strong their first match their skill ranking jumps a bunch.
For instance the example Mike Page has is a player sneaks in with a 400 rating(C Player) that plays at a speed of 600 (A+ player). Well he wins his first match and his score for his second match goes up to 586 which is pretty close. If they want to sand bag it they would have to sandbag their way right out the tournament, its beautiful like that.
would this apply to all tourneys in town ? BigDogs (multiple),Styx (both),
Gerris,Susie Q's, Donnas,etc.. I could see some players playing the small tourneys dumping to lower their handicap right before a big tourney.
