...The only reason why the toe "appears" to be rotating around the heel of the clubhead, is because it is further away from the axis of rotation of the rotating flat left wrist/hand. In reality, they are all rotating at the same rpm.

Jeff.

Precisely... all club parts rotate at the same angular velocity (which is relatively small) about an axis drawn from the grip to the CG of the club head where the net (integral ... sum total) of the centripetal acceleration is acting. Velocity is proportional to angular velocity and distance from the axis of rotation. Because the toe and hossel are farthest from this axis they move the fastest (toe towards target and hossel away from target). Because the "sweet spot" is close to this axis it moves very slowly no matter what. The notion that additional club-head speed can be had by rapidly closing the club face (as suggested by A.J. Bonar) is patently ridiculous. Rapid closing adds nil to club head sweet spot velocity at impact.

P.S.

That last statement is made with one small caveat... It may be possible that because of the fact that in a Bonar swing the club face presents a much lower frontal area (hence less aerodynamic drag) for a longer period of time, the golfer employing this method is able to generate a higher club head speed for a given ability to generate force. Lower aerodynamic drag longer = higher club head speed.
