Homer didnt invent Hinging ......he only defined its underlying geometry.

I guess you responded this way to prevent an impression that TGM is a particular way of moving the club through impact and I agree that it isn't.

But what Homer did with his hinge analysis is also a massive knowledge invention that deserves to be reckognised. He took a huge leap forward knowledge wise.

Homer created a language and a system that enables us to differentiate and analyse various hinge actions and a myriad of other important details.

If he had tied his analysis to to various methods for learning different hinge actions it might even have been patentable method.
