but most other countries are setup to only do level 6 like a level 6 scoresheet. check out any of the world or international competitions on youtube. and if you say no levle 6 then an team competing at ICU would have to have a completely different routine than they could take to worlds. lots of them do the same thing.
I don't see that as a reason. I've seen teams compete level 5 then level 6 in the same season, it's not impossible. Plus if they're never competing the progression up to level 6, how are they really prepared to do level 6 skills safely?
