She fell on the 3F and popped her lutz, and only had 1 Level 4 spin. She hasn't competed in months, though, so I would not expect her to be 100% perfect.
I wish that Sima would change her FS layout so that she only has one lutz, because every single one of her lutzes at this competition got a full edge call, and one of them is popped. I don't want those to affect her score and confidence in her comeback, especially when she's doing so well on everything else. So much progress on the axel!
