Hacking, interesting.

If you move the ball to Low-point (opposite the Left Shoulder), then the Low-Point plane line and Impact plane line are virtually touching and share the same line. Try to visualize the orbiting sweetspot of the clubhead intersecting the center of the ball. At the exact (almost) center of the ball, the Impact and Low Point plane lines and Orbit of the Sweetspot intersect.

Hit some balls from the low-point location. You'll need a tee to raise the ball and clubhead orbit to prevent the clubhead from touching the grass. Watch the clubhead orbit. It travels down and out, strikes the ball, and then travels up and in. Draw the clubhead orbit path on the ground. Hit a few more balls to confirm that the clubhead covers the orbit arc'ed line you drew on the ground.

If you wanted to move the ball 3" behind Low-Point, would you place the ball on the Target line or would you place the ball on the line of the clubhead orbit arc that you drew on the ground?

You are putting me on the spot? I guess you can't get any further down & out than the low point? That would probably mean that the clubhead is starting to orbit in & up after the low point, so that's where I would put the ball (I hope). If I am lucky the clubhead orbit path intersects the target line 3 in beyond low point (or is 3 in too little? ). I'm waiting to hear the master's voice.
I will have to wait to read it - in the morning (here).
