Homer Kelley chose to frame his ideas with precision and avoid explanation. TGM Concepts are very simple and very basic and very logical. I'm not surprised at the learning curve problem this caused. I am surprised, that given the rudimentary nature of the Pivot and Arm Motions/geometry of TGM that others haven't stumbled upon them a thousand times since. That confounds me much more than the learning curve problem.
