What a magnificent skater!
I'm no expert and can't say. But I suppose she could smile more.
If it were a low level test, they often say to hold an edge at least 2 seconds before and 3 seconds after a move - but I'm not sure that is an issue in high level comps. Maybe you need to keep your edges short to put in as many high scoring moves as she does.
I'm not sure I buy the typo error. Maybe it's just sour grapes, that someone's favorite skater can't do reliable enough triples to win. Or maybe the judge wasn't in a position to see the jump very well. They really spread the judges out, so it is hard to do it in a position that all the judges can clearly see.
They drop the lowest and highest scores, right? Was the -1 dropped, or was there another score at least as bad?
