This is why I keep coming back to thinking that we need more than 6 levels in order to ensure proper progression.
Example:
Level 1 - All non elite level 1 stunting skills, CW, RO, rolls
Level 2 - All Elite level 1 stunting skills, BWO, FWO
Level 3 - All non elite level 2 stunting skills, RO BHS, single standing BHS, FWO RO BHS
Level 4 - All elite level 2 stunting skills, RO series BHW, standing series BHS
And so on.
Will it create more levels? Yep. Will there be less competition within a level? Yep. Will athletes progress in a safer way? Yep. We're basically doing this anyway with things like 5 Restricted. In my opinion, it would help to stop people from pushing kids to things they're not ready for and throwing janky "at level" skills to get the difficulty points.
