Right on ! My explanation is to weld a putter blade on an old bicycle wheel. Tilt it, and rotate it. What you will observe is exactly what Stan is advocating, And this repeats. That's because there is no ACTUAL rotation taking place. Remember, the blade was welded so it could not have turned. It changed direction relative to the target, but not to the real life tilted plane. It just looks like it did. This is also why SBST never works. It is all luck. There was a day when Stan never admitted to this in TV interviews. But who can blame a $900 an hour putting teacher.
