Everyone here says she can't land a 3-3. The protocols I am looking at says she landed a 3T-3T in Omaha. It was ratified with no UR and plus GOE. So she can and did land a 3-3.
That was in the SP. Here's what she did in the FS: 3z, 2a+3t<, 3fe<↓, 3f<+2t+2t<, 3lo+2t, 2a, 3lo<<
I've heard several posters speak of Mirai's artistry. There was little artistry on display in the Nationals FS (I was there). She skated like a robot, with no expression either in her body or her face. But she was visibly devastated when she heard her marks. My take is that she has no realization of how badly underrotated her jumps are. If she doesn't recognize that she has a problem, there is no way that she is going to solve that problem.
