The format is straight up point system: 100 point max, 7 pts per elimination, 3 points for live players, 20 first flag pull, 50 for the hang. With 6 prelim games, 3 semifinals, 3 finals.
As far a roster player limit, I think there is one but not sure what it is, 5 or 6. Most teams don't want too many roster-ed as it takes away playing time. Of course no previous APPA history prior to this season.
