One should remember that plane angle has no effect on the plane line, it is not likely that a golfer can swing on one plane rather the goal is to make a minimal plane shift while not bending the plane line, the golfer may set up c-plane on elbow plane and at the halfway point in the backstroke the player will likely shift off the plane pads to a slightly steeper plane but the butt of the club should still be pointing at the plane line."

Thanks for that detailed reply. I have a general idea of the plane (from the Hogan book), but not exactly sure what I am even trying to do in my swing in regards to trying to stay on one plane (elbow vs. shoulder, vs. clubshaft plane), shifting to a different plane, etc...

Videos would be very helpful, or better yet lessons with an AI who has a cplane to help one use this tool effectively.
