Having judged a ton of competitions, as long as the ratio is there you are good to go with the judges. Problem is, in a division like a small division where one team will have 12 and one team will have 20, you are looking at 3 stunt groups vs. 5, pyramids are more exciting from the team with 5 groups, etc. Same with a large division - with 21 people, a pyramid section from a team with 36 when they can make 4 more stunt groups will look more exciting from the crowd's point of view.
