I've been on TM twice in the last month. It is interesting to see ball flights quantified -- particularly with deliberately employed Stroke variations. I have never used it in a teaching situation, but based on my own experiences (live with Jeff Hull and Rob Noel), I have no doubt it can add value if integrated appropriately into the lesson.

My primary purpose (especially with Jeff in the first session) was to challenge the misguided notion that a golfer cannot consciously execute a selected Hinge Action to change the Clubface alignment through Impact and thus affect Ball Behavior. No surprise here:

Of course you can.

I'm guessing TrackMan doesn't have the capability of measuring it, so they don't acknowledge it's existence?
