At 2:47, YuNa is doing a 3loop with 1/2 pre-rotation, but fully rotating on the landing (i.e. 2.5 rotations in the air.) Correct me if I'm wrong? And she doesn't even like the 3loop, so there must be better loop jumpers out there (not necessarily doing more rotations in the air, but comfortable with doing it more consistently than YuNa.)
To re-emphasize, having 1/2 a rotation off the defining number of rotations on a jump, in the air, is reasonable...and I haven't even given the ideal jumpers for the referred jumps.
It would be unwise to use Alexei Yagudin as the baseline because, as you said, he was amazing at the 3axel as well as other jumps.
