Anna's potential array of quads is far more limited than Sasha's. Sasha's 4T, 4S and 4Lz are all possible, and her Flip and Loop should also be good enough in theory. She also has a huge 2A and might have 3A potential.
On the other hand, Anna's Salchow and Loop are both weak and the Flip doesn't make me very comfortable, either. If she learns something apart from Toe or Lutz, I imagine it would have to be the Flip. I just see no hope for any other jump. Then again, she just might whip out a 4S out of nowhere. Not like her having a 4T makes any sense either.
I agree with you completely. It doesn’t seem likely at all that Anna will ever have as many quads as Sasha. Then again, the last time we all expressed that there was little hope in Anna getting quads soon, she had a 4Lz-3T-3Lo a week later. She’s full of surprises, isn’t she?
