A few days have gone and the incubator working to the limit......
Remember the quote:
"Swingers and Hitters both drive the sweet spot at the inside aft quadrant of the ball on an Angle of Approach!"
Your answer about thrust is half of the answer. The complete answer should include
"Clubhead Lag deals exclusively with the Sweet Spot Plane and is always driven directly into Impact - through a point, normally, on the inside-aft quadrant of the ball" per 7-11
Nice work!
Send me a PM . . . I have something that may be helpful to you in your studies.
