[O.B.Left]

Homer would have used the Trackman gismo as a door stop. It's a poor substitute for understanding the geometry of the Golf Swing. Knowing how poorly your stroke performs is not the first step to correcting it.

I wouldn't spend a nickle on a teacher who bought and/or uses Trackman. They should have named it the "ACME Golf Swing Fixer-upper".

Do you think the data it is able to collect is inaccurate? That would sway me.
