I think Sasha's struggles this season are mostly because she is biting off more than she is able to chew. Her 4lz always was weird. 4f even worse. She always struggled with 4s and has UR problem on 4t (judging by competition attempts) for quite some time already. Plus unstable 3a in SP. And she has to focus on all of them. What junior boy at her age has this arsenal?! I can think only about Shun - 3a, 4t, 4s, 4lo, 4lz. And he isn't jumping all of them in one program for good reason.
For now I prefer to think that her struggles at Euros with "only" 3 quads were because she was training 5 quads until EC and changed it right before competition. If situation will be the same at WC, then I don't know what to say anymore....
And about Ted:
