Jack,

I have no tone, you just keep dodging the issues. The bat doesn't start at the same angle as the shoulders, so of course the bat rotates through a greater distance. The "issue" was if THT or torque was responsible for the bat arcing a greater distance. That was the entire issue.

Here's one for you the bat doesn't start at the same angle as the shoulders, but ends squared up (unless there was more extension) with the shoulders.

You said
"I must say that I am as flabbergasted by the tone of your post as the need for us to draw this out for you. Regardless, here is a clip showing the comparison of Bonds’ “bat to shoulder” rotation"

The clip just shows that shoulder rotation is responsible for the bat arcing, it doesn't show anything about THT, second engine.

"Hi Chuck

Yes, I would say there is a multiplier effect. You could think of it as a catalyst where a small amount of energy applied during initiation can make a large difference in the contact zone. This is also supported by the bio-mechanical principle that states: “I ballistic motion, once initiated, produces trajectories that can be changed only at its’ margins.”

As and example; A small amount of rearward force applied by the top-hand during the initiation of the swing, results in much greater bat speed at contact.

Show a clip of the bat arcing prior to shoulder rotation or in response to the hips rotating.

The only way your going to convince me is by showing it once and for all. The clip of John on your video doesn't show the bat arcing prior to shoulder rotation.

Any arcing is the result of shoulder rotation. The same distance as shoulder rotation, only the bat doesn't start at the same angle. Any additional arcing is caused by momentum transfer. It is not cause by applying THT or any type of torque for that matter. The bat naturally wants to arc outwards because of the rotational force at play. Again THT has nothing to do with the tendency of the bat wanting to arc outwards.

I'll be back,
Shawn
