So, look ... In 6th event, no threat -> they can send the weaker skaters there. 7th event, Nana Araki who is a threat -> they send the stronger skaters there. Kanysheva's not in danger. She's the #1 lady for her age group and got pushed hard last season judging by domestic scoring. She also scored the highest out of every non-Eteri girl. Furthermore, Tarusina scored only 186.68, not 190. And Vasilieva can score this high for sure, if she's somewhat clean.
Vasilieva wasn't clean and scored 203.20 in Russia Cup event 1. Even if you remove choreo sequence's 4.10 points, that's 199.10. She got 29.84 and 63.76 PCS but if we assume that in JGP she receives 27 and 56 for instance, that'd still total 188.50 points. And that indeed still wasn't a clean performance for her. She lost at least 5 points for spins. Now, GOE we don't really know about but the point is, she can score 190.
