Are you sure it didn't change, even for a short time? Because (bear with me here...lol), back in may during our gym's tryouts, a coach for our J3 team mentioned they were only having 19 (21 were trying out). I thought in my head "that's stupid, why not put up 5 stunt groups instead of 4, they have enough flyers, bases, backs....". But I figured they knew what they were doing. Shortly thereafter I felt stupid because I saw the rules changes and I Could SWEAR it had said small was 5-19. Now I went and looked again and it says 5-20, but it's highlighted as a change...
