Personally I would work on staying a tad taller initially.Think ‘K’. During ‘gather’ I would try to maintain the leverage she created in the ground through the back heel for as long as possible (some eversion will/should happen) so the hip action will not be so ‘spinny’. More on a straight line. She pulloffs prematurely due to this.
Others have eluded to these 2 things. Just giving some suggestions on how to fix. Take or discard. Good luck!
