Homer knew all about the true 3-D club head orbit but preferred 2-D training and talks about it in TGM book. On page 58 in the 6th edition Homer writes “Remember, a flat plane has a straight baseline. A circle is two dimensional and can lie on a flat plane (2-D Shaft Planes).
Homer also knew about the limitations of 2-D training and wrote on page 26 of the 6th edition Homer then writes that precision is lost unless start up is three dimensional. The club head moves Backward, Upward and Inward INSTANTLY AND SIMILTANEOUSLY. (3-D sweet spot path motion).
It seems Homer felt it was better for the golfer to monitor circular motion of the club head in 2-D with a flat plane and a straight base line using the club shaft for the plane references than using the club head (Sweet Spot) with the third dimension of depth and the true 3-D orbit of the sweet spot path back in 1969. Forty years later I wonder what his take would be now.
Using straight lines for tracing the plane and monitoring alignments does have its limitations for precision when dealing with the parallel to the ground and the base line alignments. This is where I see most of the problems with golfers understanding the correct depth (in) of the motion of the sweet spot path. Golfers also have a hard time with the up part of the motion in 2-D as well.
Monitoring the back swing Swing Plane in 2-D
Starting at address using the club shaft for the incline plane reference move to where the club shaft is parallel to the ground and the base line alignment. From there move the club shaft to the incline plane as the reference to the top of the back swing. If you go to the end you will again use the club shaft for the reference for the parallel to the ground and the base line alignment. Precision is lost with many golfers at the parallel to the ground and parallel to the base line sections. Many golfers also see the flat plane as more of a Merry-Go-Round than a Farris Wheel and precision is lost with too much in and not enough up.
Monitoring the back swing Sweet Spot Path in 3-D.
Visualizing a path of the club head (Sweet Spot) moving from address Backwards, Upwards and Inwards to the top or end. Starting at address move the sweet spot on that path. Most golfers have no problems seeing this 3-D path and precision is not lost.
