Hope 3A-3T practices do not give her body too much stress.
L'art pour l'art
I hope the 3A-3T will work out. It would be great if she could do it as the combo in the short program, though that's probably a long shot. But if she could do 3A-3T, 3F out of steps and 2A - that would be 21,2 points base value in the jumps alone. 2.2 points more than Kim's layout - probably exactly the two points Kim often gets more in the PCS.
And with the new rules it wouldn't be the end of the world if the 3T is underrotated, she would still get good points for the combo if it looks good.
