Well then, in this thread some folks may have learned that there is a COP about the rear foot and the front foot, and that there is a higher correlation with swing speed to the COP about the front foot than the COP about the rear foot. In your opinion, what movement is happening that leads to higher swing speeds, and thus by correlation, more COP about the front foot?
The shift of COP, from rear foot to front foot, powered by the coil and other resistance forces in the body, happening concurrently with the launch and execution of the swing - in other words...shift and swing.
