From what you've explained, it sounds like tracing the Arc of Approach. Homer said it was an inferior procedure to the tracing of a straight baseline. I think when Homer was asked if one could trace the Arc of Approach, he said, "...sure, but why would you?".
This may sound obvious to Ted, but just for clarity to the others...
The Arc of Approach Delivery Line is covered by the Clubhead, not Traced (point at). The Straight Plane Line is Traced, and this (superior) procedure should produce identical Clubhead motions as the Arc of Approach procedure. So, by Tracing a straight line we produce a curved motion of the clubhead.
