The program is basically the same as
used for college football. See  College Description .
All teams are ranked together but the 6-man and 8-man teams probably don't belong.
There is little (but some) play between them and 1A 11-man teams.  Also the 8-man
and 6-manis a different game.  A team a little better in 11-man might win 30-17
but in 8-man it could be 75-24.
