Avalanche is defined as a loop with a snap on top (or bottom). There is no special wording that requires the snap to be "integrated". Snap rolls are by definition fast autorotations. The geometry of these types of loops is not questioned even if the snap is a little slow

If one were to do loops with half rolls on top and decided simply to do a fast roll, I don't believe geometry will change in actuality, unless the half roll was butchered. The fast half roll requires less distance to perform than a full snap roll. I am not sure why the geometry of these types of loops is being questioned.

On the other hand, one can do a slow half roll and that one should be integrated. Pilot's choice in my view as judge
