This is for players with ratings between 1400 and 1700. There is a 43% advance rate with medium-sized groups (7(1)->3) and so you'll begin with six simultaneous games. Only players with more than 100 games, less than an average of 6 hours per move, and less than a 3% time-out rate may join. There is also no vacation time. These fairly strict rules serve to improve the tournament in terms of fewer dropouts and less general wonkiness.
I'll remove players who look like they are "gaming" their score or whose score exceeds 1725, starting when the roster is full or a few days before the tournament starts. I've found that it's best to remove players when I see scores get too high, merely to keep the playing field reasonably even and give other players a chance to grab the spot.
