Then Trackman would be wrong. Baiting me isn't going to solve the problems with Trackman.

The assumptions are built into their calculations. You aim Trackman at the Target, it doesn't deal with Plane Lines. Trackman wouldn't know the difference between a Clubhead and Bowling ball.

It's a calculator with radar. It should sell for $700.00. What would Trackman read if I hit a Plastic Ball?

Of course it deals with plane lines, it tracks the clubhead hundreds of times on every swing, measuring both the plane line and the plane angle that the clubhead follows.

A couple of follow ups:

- Do you know the difference between measuring and calculating?

- What do you believe Trackman measures?
Since you seem as an expert on the subject, you must know how far the clubhead is tracked for and what that period of tracking allows the machine to extrapolate?

In Trackmans case everything is measured except face angle, the numbers are raw data presented in easy to understand terms. Face angle is calculated from these other data sets.
