I don't know where this video is coming from and if this boy is supposed to be a textbook jumper. But it sounds like that.
Single Loop jump by a little boy:
If we look at the slow-mo, the jump has a significant amount of prerotation. Does he jump any more than a 1/2 turn?
I also wonder if he actually prerotates more than elite skaters. Could it appear a lot more visible than that of 3 loop just because it's single?
I think that the point I am trying to make is that prerotation is necessarily involved in the loop.
