Consider the following three submissions . . .
1. Conservation of angular momentum allows athletes such as ice skaters, divers, and gymnasts to manipulate their rotation by altering their moment of inertia. For example, consider spinning ice skaters who pull in their arms. Since the ice is nearly frictionless, the angular momentum should stay constant during their spin. When they pull in their arms, the skaters concentrate their mass closer to the rotation axis, decreasing their moment of inertia. To keep the angular momentum constant, the angular velocity ω increases, resulting in a faster spin
The Momentum should be constant in absence of torque on the system (in our case Thrust). So as a result when your Accumulators are in their out of line condition it is easier to accelerate them. But on the down stroke they are releasing . . . so it its the opposite of the skater pulling in her arms. The system in absence of thrust would slow down. But you have thrust . . . or better yet . . . YOU MUST HAVE THRUST in order to combat the Conservation of Angular Momentum. That is why maintaining your Pressure Point Pressure is an Imperative. And also why the flat left wrist is of great importance. If you flip you are picking up speed but at the detriment of RADIUS. You want to put the FULL RADIUS on the ball through Impact. Thus the importance of Rhythm and the Flat Left Wrist. It is RADIUS POWER man.
2. the moment of inertia of an object about a given axis describes how difficult it is to change its angular motion about that axis. For example, consider two discs of the same mass, one large and one small in radius. Assuming that there is uniform thickness and mass distribution, the larger radius disc requires more effort to accelerate it (i.e. change its angular motion) because its mass is effectively distributed further from its axis of rotation. Conversely, the smaller radius disc takes less effort to accelerate it because its mass is distributed closer to its axis of rotation. Quantitatively, the larger disc has a larger moment of inertia, whereas the smaller disc has a smaller moment of inertia
In this statement consider the different discs as the different Pulley diameters we G.O.L.F.ers have as options. When the straight line motion diverts in to rotational motion of a small pulley the club WHIPS around the pulley because it is easily accelerated due to the mass being closer to the center of rotation. However with a large Pulley more hand speed is required because the mass is by definition farther from the center of rotation. But at the same time this works with you because you have more inertia and thus your Rhythm is easier to maintain with a larger Pulley. So the larger pulley is more about geometry and the small more about physics at the potential destruction of geometry if there is too much load placed on the system.
3. because the above formula can be rearranged to give v = L/(mr) and L is a constant for an isolated system, the velocity v and the separation r are inversely correlated. Thus, conservation of angular momentum demands that a decrease in the separation r be accompanied by an increase in the velocity v, and vice versa.
Note above that velocity and radius are inversely proportional. To you this means as the Lever Assembly is extended, the radius is INCREASING but the Velocity is DECREASING . . . but the Momentum is conserved in a system isolated from thrust. Mr. Kelley believed that this inevitable deceleration could be lessened by maintaining the pressure on the pressure point and driving the club fully down and fully out on-plane not disrupting the orbit.

Can you site your sources of where Mr. Kelley believe that and/or believe this? If they're from the book please site section and/or page numbers.
