So, it isn't so much the clubhead moving inside out as it is the clubface, being slightly open, contacting the ball on the inside aft quadrant?
You're gaining on it, Bigwill. You keep on truckin,' and we'll keep on fillin' in the blanks!
At Impact Fix (7-8 ) you erect your selected Inclined Plane Angle (Clubshaft Control) -- ideally the Turned Shoulder Plane (10-6-B) -- and align the Clubface (2-J-1) in accordance with the desired Hinge Action (Clubface Control) -- slightly Open for Horizontal Hinge Action (Swinging) and slightly Closed for Angled Hinge Action (Hitting).
The whole object of the Stroke is then to return to these pre-set, precision alignments with the required Power (Clubhead Control) and then to Drive through Impact to Both Arms Straight. It's as simple as that.
