I feel bad for Tuktamysheva, but despite her impressive comeback I suspect the Russian fed just feels she isnt much of a prospect moving forward. Also at NHK despite skating perfectly she not only lost to Kihira, but Miyahara too. Someone like Medvedeva would never in a million years skate cleanly and lose to Miyahara, not even in Japan. And Miyahara not only beat her on PCS (predictable) but jump GOE even with her tiny little jumps. If you look at the protocals Miyahara got higher GOE on almost all her clean jumps than Tuk. on hers, which is what barely inched her in front, along with the much higher PCS and some higher GOE on spins, despite the much lower base value. Kihira meanwhile slaughtered her in jump GOE in addition to a higher base value. And jumps are supposed to be Tuktamysheva's strength.
And frankly with Sofia a late blooming riser who looks to be getting stronger, Medvedeva and Zagitova still around, and all the up and comers, Tuktamysheva has no real shot moving forward. I can see the Russian fed. logic in not sending her, now that there is valid excuse/rational behind considering not to.
