I have a same feeling though if Polina skates relatively clean with minor mistakes her PCS will probably be higher than Courtney's. Isn't interesting that both have Russian roots - Polina's mother is Russian and Courtney's three grandparents are Russian?
I agree, I think it could be really close between those two. A clean Courtney would probably get the technical edge, depending on how strict the caller is on UR which Polina has been prone to this season. Polina should beat her in components, though I hope she has improved her speed and power since the GP.
