Hmm, if the 3A (called <, BV + GOE = 6.13) she attempted in the SP and replace it with 2A (assuming it will be Finlandia standard, BV + GOE = 4.68), the reduction in SP scores will be from 76.55 to 75.10. If there is no 3A in the FS, I am going to assume that her FS layout will be similar to what she attempted in her junior season plus a choreo sequence. Using her junior GPF FS scores as reference (TES = 74.37) and adding in the possible scres for the ChSq based on her IdF attemp (BV 3.00 + GOE 1.43), her new theoretical total TES without 3As will be 78.8 => reduction of -9.58. Assuming the PCS all stayed constant as per IDF programmes, all the reduction in tech scores for both SP and FS = (-1.45) + (-9.58) = -11.03. Which means that her total score of 236.00 will drop to 224.97. This will still put her comfortably above Alina Zagitova's 216.06.
Thus, it is not really the presence of 3As alone that allowed her to win. It is a combination of high tech GOEs coupled with way above average presentation skills that ensures the judges cannot blatantly lowball her in PCS (or at least not that obviously low), that allows her to stay competitive even as a first year senior with Zagitova and he more senior skaters.
