maybe the reason why Ben Hogan wants 3 right arms still for swinging..

Ben wanted three right hands because ideally he wanted more pivot speed which was ultimately sensed by the right hand as lag pressure.

If you truly know hitting and truly know swinging, the lag pressure is similar, but the effort in creating the lag pressure are worlds apart.

In Hitting, there is no pivot pull except in start down for a 4-barrel stroke. Once start down is completed, that's it for the pivot except to passively support the rest of the motion.

In Swinging, there is no right triceps thrust except for extensor action which is essential for maintaining the power package structure. So besides extensor action even in the most powerful flywheels, the right triceps duty is to maintain the structure so it doesn't break down (quit) under the forces of centrifugal pull, increasing lag pressure, and ball compression. The right arm may feel active, and it is to a certain degree, but it is passively supporting the motion; i.e. it isn't driving the motion except for a true right arm swing.
