[Amen Corner]

Do you want to participate in a discussion or Bait me?

If it doesn't measure face angle between impact and separation then it doesn't know the effects of a Horizontal Hinge. It's based on a "Collision Theory" involving "Glancing Blow" to Back-end-calculate face Angle from Ball Spin. That's my problem with Trackman besides the ridiculously high price for using 30 year old technology. The Profit margin for that toy would make even "Bill Gates" blush!

Then, just like anything advertised today, they package it by claiming "New Science" and "New Laws". As though the Laws of physics have ever changed. Someone soon will have a duplicate machine for half the Price. Then Trackman will announce "New and Improved Laws".

I feel that the profit margin comments are totally unnecessary! It raises the question if you have an agenda with the company.

Just want to mention for you consideration. Face angle is not calculated from ball spin as you seem to believe. If it were calculated from spin we would never see the discrepencies created by off centre hits.

So my suggestion is to leave it to what it is at the moment with no more guessing from your part until you have spent time with a TM. Then this discussion could continue.
