In a true Three-Dimensional Impact (Down, Out and Forward), the circumference of the Ball lies interior to (or "inside") the circumference of the Clubhead orbit. Specifically, the Ball lies interior to the orbit of the Leading Edge of the Clubface. Thus, during Impact, the Clubface and Ball become one unit within the same orbit, welded together at the Point of Compression.
In the Upstroke Motion described above, the circumference of the Ball lies exterior to (or "outside) the circumference of the Clubhead orbit. This means that the Ball will be struck by the Leading Edge itself and cannot be 'trapped' within its orbit. Thus, the Compression Point is lost, and the Ball simply rotates away.
Will the Clubface and Ball be welded together (same Impact and Separation points) during Impact with the uncentered motion of Angled Hinging? What implications, if any, does this have on the interior/exterior argument above?
