The audio accompanying the photo makes it patently clear that Yoda is indeed demonstrating the sustaining of steady driving pressures and he reminds Colin that is to be his goal for the rest of his life.
The pic interested me because the alignments depicted were probably arrived at while Yoda's concentration was elsewhere thereby allowing an insight into what comes naturally. Of course this was all conjecture but being a chronic experimenter I tried a few swings with the picture above in mind and found it improved accuracy with my short irons. This may have been because of my tendency to over-roll the left wrist, close the face and hook the ball but in any case I enjoyed the experiment.
It also lead me, rightly or wrongly, to have a closer look at what Homer had to say about 10-2-D “This Grip Type features maximum Wristcocking action and strong support for both Acceleration and Impact loads. The palm of the Right Hand moves toward Impact exactly like a paddle-wheel rotating On Plane—no separate Rolling Motion until after Impact.” which probably helped with my over-rolling problem.
I appreciate the insights from all your posts and have taken them on board.
