TGM perfect?

[airair]

What do you say to what Michael Jacobs says about TGM, that it is old-fashioned in some areas:

--

3D analysis of ball - club - body has provided a lot more valid scientific information that The Golfing Machine does not provide at the moment.

To name some quickly:

Hitting & Swinging

Hinging

Heavy Hit

Geometry of the stroke

Component List

Would love to see it get updated!!! We will probably get into this area much more in the winter time
