O.K. last one and I'll wait for some answers. I look at what I write and it makes sense to me but I read it and I actually don't make sense. Before release she pulls her hips to about 45-50 degrees and then the hand passes through, release, then the hips complete the close.
(4) As to "right way" to pitch, the hips have to open for the arm to go by. After the arm goes by, the hips close. There is no other way. There is some debate as to how much the hips should close after the arm goes by the hips. Ueno closes her hips more than Finch.
