PP2 on the BOW side of the shaft?
 

If PP#3, the monitor for the hitter is at the AFT side of the shaft.
Then would it not be logical that PP#2, the swing monitor pressure on the left hand be felt in FRONT on the shaft along the last three knuckes?
Or because swinging involves Drag loading along a radial geometry, should the pressure of PP#3 be more uniform AROUND the butt end of the grip?
