No way the vertical hinge score lines point at the left shoulder socket.

If the score lines point at, i.e., are 'in the same plane with,' the Left Shoulder socket with Horizontal Hinging, they also point at -- are in the same plane with -- the socket with Vertical and Angled Hinging.

Per 6-B-3-0:

"Accumulator #3 should never be Out-of-Line -- instead, it seeks to MAINTAIN its radial alignment with the Left Arm and a Left Wrist vertical to its associated Plane."

From the Glossary:

"Flat and Vertical Left Wrist: Positioning the Left Wrist to be vertical to its Left Shoulder Axis and to its Associated Plane during Impact."

Each of the three Hinge Actions represent a valid Clubface Control. Each has its own distinct Rhythm (2-G). And each maintains its radial alignment with the Left Arm as controlled by the Flat Left Wrist vertical to the Left Shoulder Axis.

The difference in the three Hinge Actions is Clubhead Travel and Clubface Alignment (relative to the Plane Line). In one word, the difference is Rhythm.

Not the radial alignment with the Left Shoulder Axis of the Stroke.
