In general, I have few comments.
It seems that Mao, apart from her flutz, did also a lot of small 'mistakes'. EVeryone spotted something - scratchy spirals, a sloppy spin, some parts off the music. Than, it makes me wonder, why is she scored so high?? She might have 3-3 combo, but still, jumps do not make figure skating...
I am very confused with what the competition should look like.. Because, on the one hand, I would prefer to see in the 1st place a skater that skated flawlessly, although did not do such difficult jumps (for example Sarah Meier). On the other hand, I realize that this is sport and everything needs to be counted carefully, otherwise the scores would be COMPLETELY dependent on judges preferences. Therefore, as a partial solution to this problem, I think that in SP all the technical flaws should be punished much more - for example, if normally you lose 3 point by flutzing, you should lose 5 or so. If you do a stepout, it should be punished more (btw, I dont understand why a stepout is considered as a such a minor mistake, actually it looks horrible to me). Then, those great skaters like Mao and Kostner, would have to provide super good FS in order to get to the podium. And thats fair. Otherwise, they make mistakes in SP and they are still rewarded with top spots.. At least their score difference should not be so high compared to the rest of the field.
