It's not just a matter of quads vs triples, tho.
Toe and Salchow are jumps where your hips are "open" to rotation at take off, as such it's just the movement you are doing that "cause" some rotation on ice before the actual take off.
When you do Loop, Flip and Lutz your hips are "closed" to rotation, but: with loop some degree of pre-rotation is again natural since it's an edge jump (so you don't have a "snap" picking up moment). Flip is not counter-rotated like lutz so it's normal if you have a tiny bit of prerotation more.
It's not by chance, imo, that ISU speaks about "cheated jump" when the prerotation goes to 180° and over, because a bit of PR is considered normal and just in the way you are supposed to take off. The only jump where you should have next to nothing PR is lutz, since pre-rotating it would mean doing everything but a lutz :wink:
sorry, i should edit my post to say most jumps have PR instead of quads
The thing about when prerotations >180 is that the skater probably does it too fast for it to be picked by up eye and they can't slow-mo it so what's the point....
