6-E-2
"Actually, when in doubt there is always the impact fix hand location procedure."
"The Machine delivers the #3PP to impact fix hand location at impact with all delivery paths, delivery lines, pulley sizes, etc, because it structure is designed to do just that."
I set straightaway ball flight location according to the built-in forward shaft lean of each club, and glommed onto the above quotes from 6-E-2 The Aiming Point Concept. And visualize the angle of approach as parallel to the angle of the right forearm at on-plane impact fix location, and occasionally monitor the clubhead blur covering it.
