It doesn't mean that. PCS are not equal with artistic impression, though good artistic impression can boost your scores. You can still score high even if you are not an 'artist' on ice, you just need to fulfill other requirements defined by PCS.
In an ideal world, you are right. But it does not look like judges really divide the categories or look for keypoints, they just look at the whole package and give roughly the same score for everything.
Take 'artist' Anna VS 'technical' Sasha: I would expect way higher SS by Sasha and Int by Anna. Now, what do we get?
In the end it will come down to reputation and fed support anyways. But I'm curious about the PCS devellopment of 3A this and next season.
