Surely this would have to be very idealised, at least for an iron shot. As low point is usually underground separation would occur once the club had entered the ground, lowering separation clubhead speed.

For a non-idealised application, the further back the ball is played the more the clubface is closed to the left arm wedge? Would the hookface built into clubs have something to do with it also? Perhaps the non-ideal ideal is to align the wedge with the (theoretical) leading edge if the clubface was not hook faced (just a thought which could be very wrong!!!!)

2-J-1 IMPACT ALIGNMENTS The geometry of all alignments stems form the Impact geometry requirements. So, the first step in preparation for a Golf Shot is the establishment of the Impact Conditions. See 7-8. The Clubface must be exactly square to the Target Line (10-5) only at the Point of Separation. So the Clubface alignment at Impact Fix must fit the selected Hinge Action (7-10, 10-10). For Horizontal Hinging, it is Slightly “Open” at Impact Fix to allow for “Closing” during Impact. The longer the shot, the more “Open.” Angle Hinging gives the Clubface a Slice producing uncentered motion so while the Clubface does “Close” during Impact, Clubface alignment is slightly “Open” for short shots but for longer shots it must be set up more and more “Closed.” The alignment for Vertical Hinging and Cut Shots are the same at Impact Fix as it is intended to be at Separation because these are “No Roll” procedures. Alternative alignment procedures are presented in 7-10. The Machine (1-L) is positioned and adjusted to the Stroke – not vice versa (8-0). Remember – the Impact Point must become “On Line” at Separation.
