You say, "The referenced Bending would take place after the Hinge Action but before the Finish Swivel (back to the Plane) is completed. Admittedly, these are split-second differentiations, but they are necessary for Precision Golf. Why? Because the Ball knows."
In both cases the Ball is gone before the Bending, so the Ball CAN'T know.
The Golf Stroke is an integrated whole, and always before any Action there must be a 'preparing.' It is this preparatory move during Impact that the Ball knows.
I thought we were talking about, how the ball could know about a Left Wrist bend, which happens past separation. What on earth does this last statement have to do with that????
