It is not clear to me why you would think that the hand arc path near impact and post-impact would depend on release type.

My main interest, in posing this question, is whether the hand arc post-impact is relatively "fixed" for a good golfer who stays on-plane - because his hands have to move along an overall arc that depends on the angle of his selected inclined plane through the impact zone and the "fact" that he needs to continuously trace a SPL while his hands move through the impact zone.
