The ISU is really out of their minds now. Not only the solo triple rule but spins too. Whether Polina did get the requirements or not, she still executed a good sit spin yet it receives exactly the same marks as Kaetlyn's flying camel spin which she fell on. I mean, seriously? Polina actually did the spin, and spins may not always be easy. The ISU should do something like "your butt has to be below the knee to receive level 3" or maybe "you need _____number of revolutions to receive level 3" instead of invalidating the whole spin just because ONE requirement was not met, whether the difference was big or small.
I guess it's possible they considered Polina to be too high in her position AND also didn't complete a certain number of revolutions for a single spin but they should still award her for actually spinning.
As sad and cruel as it is, it SP is a technical program. Meet the requirements or you pay.
It's cruel but this is top level competition. They did this because there was a feeling a couple of years ago that the IJS rewarded too much for errors (e.g. Patrick Chan- and 'inflation' as an example). Not so much anymore.
