Great stuff. How about wrapping up by discussing in which direction the slab of grass (or piece of cartpath) should be flying - relative to the target line and/or the initial ball direction? Or did you just say that? On Line Divot
I would say that the Line-of-Flight of the Divot depends on the C.O.R. (Coefficient of Restitution) of the Divot.
The shorter the time the Divot stays on the Face of the Club -- or the more Inside-Out the Impact -- the more it will tend to fly to the right of Target (on the Angle of Approach). The longer the time the Divot stays on the Face -- or the less Inside-Out the Impact -- the more it will tend to exit to the left of the Target (on the Arc of Approach which may well be left of the Angle of Approach).
Bottom Line:
Keep your Left Wrist Flat (Left Forearm and Clubshaft In-Line / Rhythm per 2-G -- Roll, No Roll or Reverse Roll Feel) while you Trace the Straight Plane Line with your Right Forearm and #3 Pressure Point Lag Pressure.
