Well just going by this, looks like Anna would need mistakes from Kamila as she will have SP advantage. If Sasha went completely clean short and long, do you think she could challenge a clean Kamila? Or are her GOE/PCS just too high for Sasha to overcome?
No. Even with a 3A in the SP and a completely clean FS (a constellation she has never produced in her entire career), I cannot see Sasha overcoming Kamila, since her GOE and PCS are just so much lower (and imo rightfully so.)
Anna with this layout could definitely beat Kamila, but unfortunately she does not have this layout.
And that's the simple explanation why Kamila is winning. Anna has the performance component the win, Sasha has the technical component to win, Kamila has both.
+ a reputation and momentum bonus she has established for herself over this season, including and especially here in the Team Event.
Edit: I would love for people to stop complaining that Kamila doesn't perform or emote. That was the case last season, but anybody who has actually watched the Team Event should have seen that she is trying her absolute outmost to interpret the music. Including facial expression, being on the music, finishing the movements into her fingertips etc. The "issue" is just that she has a generic and lyrical SP and a completely nonsensical FS. She is a snake skating to Bolero ...

- I for once would not have a clue as to which facial expression I am supposed to be emoting there.
In contrast Anna's FS is dramatic and climactic and actually based on a fictional character she can portray. Same goes for Sasha's theme, which is sassy and agressive. Those are much easier to interpret imo.
