I thought a quick look at Percy Boomer’s principals of the golf swing would be interesting.
Here are his six essentials- let see how they translate into TGM. Please add and/or correct what I have written.

Any thoughts?

In addition to his thoughts on the Pivot, Percy's biggest contribution was his then radical insistence on the In-To-Out Stroke. His line drawing illustrations were compelling and unequivocable: They left no doubt as to his position on the subject.

It was his ability to communicate to his students this concept of the true orbit of the Clubhead -- to Translate the necessary Mechanics into each student's own Identifiable Feels -- that made him the most sought-after Golf Instructor of his time.

And it was his ability to communicate his concepts via the written word that earned him his place in the pantheon of the immortal golf writers.
