Correct I was not clear - when the ball goes absolutely dead straight (zero curve) - TM will read 0 path 0 face angle. You really need to experience it for yourself. Sean Foley wants his players to swing 3 degrees inside out with a clubface roughly 1.5degrees open. Results in tight little draw at the target.

Wow, interesting stuff. I watched the videos on the TM website. When they say "Path" they are talking about "Plane Angle" meaning that a Steep Plane might be 3 degrees inside-out and a shallow plane might be say 5 degrees inside-out. They aren't talking about the Clubhead crossing the "Plane Line".
