What seems to be a problem with some skaters? Here are some examples that have been battered around in this forum:
Shizuka - the last part of her triple combo is cheated.
Plushenko - similarly that last jump in the triple combo.
Weir - travelling spins.
Yukina - underrotated jumps.
Michael - the quad lutz.
I wll be looking for the above this season. I'm not sure these are constant errors (maybe Michael).
Are there others with errors you will be looking for?
