They are the same in that they both describe the late Release as a small pulley wheel and the early Release as a large pulley wheel. But there the similarity ends. Dante's analogy has to do with the inertia of the wheel and its physical rotation. Kelley's analogy, on the other hand, has nothing to do with either. Instead, the wheel is a proxy for the Release Interval -- the size of the Release Arc through which the Hands pass -- prior to Impact. The smaller the Arc -- the less Clubhead Travel Time permitted during Release -- the greater the Clubhead Speed. For example, halving the Travel Time (Snap Release / small pulley wheel) doubles the Travel Rate (Clubhead Speed). Conversely, doubling the Travel Time (Sweep Release / large pulley wheel) halves the Travel Rate. All this is necessary to comply with the Law of the Flail and the Rhythm (RPM) of the Stroke as the Clubshaft seeks its in-line condition with the Left Arm. In other words, Kelley's model has to do with the increase (or decrease) in Clubhead Speed with the Handspeed held constant. And that Clubhead Speed is inversely proportional to the diameter of the pulley wheel, i.e., the smaller the pulley wheel (at the end of the Delivery Path of the Hands), the greater the increase in Clubhead Speed during the Hands' encounter with it. __________________ Yoda Yoda View Public Profile Send a private message to Yoda Visit Yoda's homepage!
