Valid question.
You can physically work on both the 'pause removal' and 'hand path'.
That said, I would personally work on the 'pause removal' first, then evaluate the 'hand path' without the 'pause', and work on improving the 'hand path' from there.
Why? Because the 'pause' has multiple negative effects ... including the insertion of a 'rush condition', which negatively impacts the 'hand path'. Hence the notion of first removing the 'pause' and then perfecting the 'hand path'.
Fair enough. It seems like it was an easy fix but the hand path / arm usage remains the same. Now on to the hard part, DrDrodd. I don't mean that in a bad way - it's just that I never thought the pause was a big deal and your daughter proved that. But, the way she delivers the barrel to the ball is a big deal. It is harder to overcome and will take some work on her part.
I agree with Butter on the 'hand path/arm usage'. Seems to create a 'push' type swing. Also I'm not a fan of the ER of the rear leg. Would like to see the rear leg remain stable during the load/coil.
On a side note I think there is something to be learn by watching the 'magic carpet ride'. Weight shift......
