Kinda. Here's what I'm saying . . . imagine you have a string with a weight on the end. You start swinging it around in a circle with some of the string still left in your hand. Now you let some of the string out so the radius effectively just got longer. Assuming uniform circular motion (you don't add torque or force to speed it up), angular momentum will be conserved. So when you had the relatively smaller circle the weight traveled faster in terms of RPMs. But once you extended the radius the RPMs (angular velocity) DECREASED inorder to conserve angular momentum (=MassXAngularVelocityXRadius). The mass is constant so when the radius gets bigger or smaller as a result the RPMs must increase or decrease accordingly. BUT . . . with the larger radius you are picking up Tangential Velocity as a result of the weight being farther from the center of rotation.

So basically radius increases then angular velocity decreases BUT tangential speed increases. This is what Homer meant by Surface Speed. The RPM of the entire system is decreasing as the radius is extended but clubhead speed surface speed increases geometrically as a result of the EXTENSION and not the effort to create more handspeed.

This is why Homer said the Swinger needs a quick start down. As a result of the lever assembly being out-of-line due to wrist cock it is easier to accelerate because its moment of inertia is smaller (think of the string deal with the smaller circle). With a smaller radius you can really get the thing whipping around (accelerating angularly) fast. So you have jacked up the rpms of the system via the out of line condition (shortened radius). Then as the lever assembly gets extented via the uncocking surface speed gets multiplied because the clubhead is further from the center. Thus Homer says the Swinger cranks the gyroscope and then just hangs on. You don't need to "add" you just need to EXTEND. The extension is the mechanical advantage via the conservation of angular momentum. It is LAW. Law don't take no lunch breaks.

I find this portion of this quote fascinating.

I see a very short radius in Phil Mickelson's swinging motion. I think he keeps his radius as tight as possible.

Is this in line with what you were saying bucket?

I really messed around with this concept yesterday via a straight line deliver with a hard rope pull maneuver. Driver speeds increased by 5mph instantly and my hands were much further forward at the delivery position.
