I wouldn't know. I haven't watched any of their videos. I just know when a squad stunts a lot, and makes it look easy, it's going to up their overall impression score, as well as their choreography and creativity scores as well. Typically SE makes stunting look easy. Obviously their mistakes are costing them, based on the 4.5 in deductions they had this past weekend, assuming some of that was from stunting...
The point I'm trying to make, and this goes for ANY team, is that regardless of whether you've "maxed out" your difficulty in a certain category, if doing MORE than what is necessary is impressive to the judges, it's helping your score, guaranteed.
