No, I'm saying that it's negligible that Slutskaya was at the time incapable of doing a 3-3 and Shizuka was capable of doing a 3-3, since neither attempted a 3-3 in either program anyways.
Plus there's no guarantee that Shizuka would have landed her 3-3 even if she had attempted it, just because she was landing them in practice, so it's a moot point. Was Shizuka landing 3-3's in her program run-throughs or just when trying the 3-3's separately? Was Shizuka landing 3-3 in the warmup of the SP or FS? (Again, doesn't matter because plenty of skaters have clean practice run-throughs but can't land the big elements or dilute their programs come competition.)
