If you look at her GOE marks for her elements there was only a slight elevation from what she got at the GPF; the bump up happened in PCS which is quite common in National competitions especially when you add in that she's a 2-time defending national champion, roughly 5 points in each program, though the FS at the GPF did include a fall without the fall it likely would have been a little higher and it was also in her first senior season. And the Russian Cup has the weird bonus point eligibility thing that I don't quite understand that international competitions do not have.
SP PCS: GPF = 34.55; Russian Cup = 37.20
FS PCS: GPF = 69.13; Russian Cup = 74.24
Are her scores inflated, yes but this is the first event, so I doubt she will be the only top skater getting inflation. Also, her scores here are so much higher than everyone else because she did the most most difficult technical content by a long shot, back-loaded the most difficult 3-3 combination in the SP, in the FS landed the only quad and did three 3-3's, 2 of them being back-loaded, and she was mostly clean on those elements.
