Imagine looking at this clubhead path from down the line. It wouldnt be flat, no. Close ish though, flatter than most. Plane angle shifting being responsible to large measure . Hogan got a little laid off at times .... some say for a purpose . This was a topic of discussion in Homers GSEM class in 1982. But I digress....
Would this non flatness of an ultimate golfers actual clubhead orbit when viewed from DTL render the flat as a pancake Geometry of the Circle mode of examination irrelevant? IMO no!
I love this animation . Imagine if you looked at a [B]tracer line[/b] of the animations clubhead travel through 3 dimensional space! It'd be unlikely to attribute its Picasso like meanderings to being the product of circle laying flat on an inclined plane , which is shifting up and down (variety of manners possible this is but one). But , Homer and most likely others ahead of his time did.
