Sure, it is a possibility that Tutberidze gets all the spots, but even in that case there is five(or maybe even six, if Medvedeva is back strong) Tutberidze’s girls who wants the spots, but only three spots. Valieva, Scherbakova and Khromykh all have quads. If Valieva and Scherbakova skate the way they did this year, it is very likely they will get one spot each. So that leaves us with four girls fighting for the last spot (and that’s even not counting non Tutberidze’s girls such as Trusova and Tuktamysheva). Even if Khromykh didn’t get the spot, there is not much Kostornaya can offer that couldn’t be matched by Medvedeva or Usacheva? Sure, she had 3A a year ago, but since then her figure completely changed and no one has seen her to land it for over a year. She also heavily relied on high PCS, which Medvedeva as a past world champion will get too, and on high GOE, which Usacheva will get too because her jumps are huge. I can’t see anything that could make the selection towards Kostornaya rather than any other skater.
