[Yoda]

There is no opinion, there is no style, only facts. The right forearm has to move 3 dimensionally in accordance to the secondary lever assembly motion on the inclined plane in order to have the clubhead traveling in a consistant orbit. If you set the mass or weight of the clubhead off in an incorrect orbit initially, you will be working against the physics of gyroscopic motion requiring compensation later in the backstroke.

Mathew is not an Authorized Instructor of The Golfing Machine quoting chapter and verse. Instead, his authority comes through extensive 3-D modeling of the Golf Stroke, some of which is copyrighted and appears in the LBG Gallery. He learned quickly that computer models respond only to geometrical precision, not to vaulted opinion.

It is this geometrical precision that Homer Kelley referenced in 2-F (Plane of Motion):

"But precision is lost unless Start Up is a Three Dimensional parallel to the Three Dimensional Impact, i.e., the Clubhead moves Backward, Upward and Inward -- On Plane -- INSTANTLY AND SIMULTANEOUSLY." [Capitalization emphasis by Kelley.]

And it is this geometrical precision (and its resultant Compression) that led Homer to the Right Forearm Takeaway.

He didn't just 'make it up.'
