How far the nose breaks has nothing to do with it being a snap or not. In other words the nose just has to break the plane for it to be considered, not by any minimum amount of degrees.
That full scale pitch varies according to aircraft also. You may not see a huge break in a full scale snap either, it depends on the entry method. I have seen some experimental's with very little nose break when they attempt the use of ailerons in the snap (like models). Hense the argument of was it really a snap or a bump of elevator with a extreme roll rate.. These same questions came up in the full scale area as well (at least when I was a little involved in the 90's).
I am not trolling here either, I like these discussions. And beleive it or not (even though I will never admit it) sometimes I am wrong and need to be corrected.. It has been a few years since I have gotten to discuss the actual maneuvers, and I can't wait to get my first of many zeros so I can moan and groan.
