Another question:
What's to keep players from gaming the system by chasing more matches per week?
For instance:
froyo has two matches early this week, and ELV has 1 later.
What's to keep someone from swapping from froyo to ELV players between their matches and picking up double points?
Or, less nefariously, dropping players on their 1-match week and picking them back up during their 2-match week, ultimately accruing extra matches on the books?
