Clubshaft can be forward but should not be less than vertical at LOW POINT.
Point of Seperation is not the LOW POINT of the Clubhead Arc.

From Release to Follow-through, the proper rotation of the Left Forearm (6-B-3-0) maintains the precision Alignment of the Left Arm Flying Wedge (6-B-3-0-1). This Alignment dictates that the Clubshaft remain in the Plane of the Left Wristcock Motion.

Assuming the 'Left Wrist Vertical to the ground at Impact' procedure (7-10), the Clubshaft position at Low Point will be determined by the Ball Location and the Clubhead Travel (Rhythm) of the selected Hinge Action. Assuming the 'Left Wrist Vertical to the ground at Low Point' procedure, the Ball Location will be at Low Point, and the Shaft will be vertical, regardless of the selected Hinge Action.
