IMO its a visual guide line with (given the degree of inclination to the plane) an associated club head blur. A guide line for the Release of Accumulated Power. You have to know where to aim all that power.
Assuming Tracing and the arc of approach procedure.
At Top you should :
See the straight line Base Line
Mentally prepare to uncock down plane towards the base line .
Mentally prepare to Roll on plane, "down the line" and see the associated club head blur. The blurred arc of the club head's on plane path.
People tend to: Not uncock down the plane but forward on plane. Steer the face towards the hole. Steer the club head overtop of the straight line plane line...."covering the plane with the club head". All bad stuff geometrically. All very common. To change that you need to change your intentions.
Thanks OB. Any advice on how to Release/Roll #3 after starting to Release #2? Or should you be only thinking #2?
How you think Hogan did it with a Bent L wrist on Top? From Top, Drag Load, then just #2 down on plane/baseline with #3 being released "Automatically"?
