2-K Pulley Diameter
From 2-K:
Quote:
When the Belt starts around the Pulley (Release) its MPH does not change (Constant Hand Speed) but the Clubhead goes into an Angular Motion and its Surface Speed becomes proportional to its: 1). Radius, 2). Belt Speed and 3). Pulley diameter. Increasing the diameter and/or the Belt Speed increases Clubhead MPH and vice versa.
Is this a typo? Why does increasing the Pulley diameter INCREASE Clubhead MPH? Shouldn't the Surface Speed of the Clubhead rather be inversely proportional to the Pulley diameter (the smaller the Pulley, the more Clubhead speed will pick up when the Belt goes around the Pulley) - as in 6-N-0 and 7-18?

Or am I missing something here?
