so it is correct to say that the straight line thrust(straight line delivery path) of pp#3 is STRAIGHT LINE to the BALL and NOT straight line to the HAND LOCATION AT IMPACT ?
or more simply, does every STRAIGHT LINE delivery path go to the BALL and NOT IN FRONT OF THE BALL ?
Well . . . I would say that Straight Line Delivery Path is to the Aiming Point which could be the Ball, infront of the ball, or behind the ball. All would be somewhere on the selected Delivery Line. The Clubhead seeks out the Delivery Line not the Target Line. But the effort is Straight Line DOWN AND THROUGH regardless of location of Aiming Point or Pulley Diameter.
