The point I'm making is that you can also do the same plane shift with a Swinging motion and the same release point, which would give a blur which appears identical to the player.

By plane shift do you mean a shift up to a club head only eye plane or out to the right 10-5-E . I assume you mean the former... Sorry don't follow. If its the latter and your swinging its just a closed plane line.. Inside out stroke. Draw shot procedure typically with a curved blur.

The true geometric Angle OF Approach Procedure where the club head is seen to travel a straight line delivery line is very un swingerish. Full on manipulation , non shaft planar ..... not a rock on a string deal more of a right arm and club shaft describing a cone shape .... Its a bit of a weird duck.

And this is where my thinking runs into some trouble because Homer in conversation with Yoda said Arnie was a hitter who used the Angle of Approach . But when I imagine what Arnies blur might have looked like to his eye , I think it must have been a curve given his plane angle. Something Yoda wondered about too and wrote about on this board. This is one reason why I differentiate the true Angle of Approach procedure ( where the golfer sees the straight line) from the hitter with angled who points his plane line 10-5-E but sees a curved blur. Two different animals. Both hitting.

If you go far enough down this path you get into the meat of Homers ball flight laws. Something we can now prove or disprove given doppler radar ... maybe. He was way ahead of the curve on this but Im not sure what his batting average was ... really really good but a perfect 1000 ? I dunno that'd be amazing for a guy who worked with only a pencil, paper and one heck of an inquisitive mind. What a story!
