When I say I would like for you to set up with a Trackman behind you when you do your videos, I am serious. I sincerely would like to see the numbers on your correct execution. You can rent a trackman for short duration. Wont trackman give a set of numbers that repeat if your stroke repeats? Wont there be some measurable data we can use? Your trackman numbers then, whether it captures the geometry perfectly or not, will give us more observations about how to correctly apply the geometric knowlege. I am not a stack and tilter but it seems they are making a similar video to be released soon that incorporates trackman. Would like to see that done from a more pure TGM approach. Your thoughts?

I would hope that Trackman will record the Ball Flights accurately and compute any minor differences in Geometry. That's not the problem. But, a problem does exist if you look at the numbers in the above video and conclude that a Driver should be swung with a different geometry than a Nine Iron. That they can be different is not the problem either. That they "Should be different for the same Player" is the problem.

In the above video, Trackman shows that it's possible to use different Plane Angles and Angles of Approach and Attack and still result in a straight shot. Really??? is that new??? No, of course not. But the teacher concludes that that's just the way things are. That's why I have a problem with the video and the teacher. That's not the way things are, should be or need to be. In the right hands, Trackman should be an asset to the teacher, but in the wrong teachers hands, it will be the undoing of a potentially good player, who's paying big bucks while being led to believe that this is the best solution.

Trackman is a TOOL. And, as it is with all "tools", it's ONLY as good as the person who uses it. If you as a teacher don't have a firm grasp of golf alignments, then maybe you should learn these first before you spend good money on an overpriced piece of equipment. The teacher in the video is very confident that what he teaches is fundamentally sound and correct. Nothing new about that, either.
