[O.B.Left]

You can if you start from after the Shift. I only had to ignore two frames at startdown. The red dot on his left shoulder is his hand location at the third frame from the Top during the downstroke.

The guy swings On-Plane.

OK but then you shouldnt have closed the circle at the top maybe? A smilie face during Elbow Plane would be 2D, planar. Or you draw the Angles, like Homer did in 10-23...... Hogan didnt shift much though in terms of degrees...................but just saying.
