Since the BKR ranges for different games are different, it would be nice to be able to specify a different BKR range for each game. For example, if you want to set up a tournament in Backgammon and Nackgammon, there is no BKR limit that will identify, say, the top 10% of players in each. If you set the lower limit at 2100, you won't have a Nackgammon tournament, and if you set it at 1800, you probably won't get the backgammon tournament you wanted.
