I am trying to find the place that would possibly explain the "circle"thing,I thought it related to the 2 bones in forearm being rotated,turned anti-clockwise at top,and then unfold forearm on downswing into the "underarm " toss,at top ,it would have to resemble ,or in fact be chicken winging,so if the toss was starting from the top into pitch,it would have to be in form of circle.........heh heh i think

Don't get hung on what either Mike used as buzzwords.
He threw it around the circle (the swing arc) with the shoulders, the fastest moving part of the body, and Dunaway demonstrated that in his Iron Byron analogy.
Body, arms and hands are three separate zones and power comes from the arms, but not independently of any other part of the power package (which excludes body. The right shoulder is the last component of the body and also the first component of the power package.)

What they failed to mention is that Austin laid off the shaft in startdown, which has some benefits re: OTT and throwaway.

And he added right arm on entry to the release area. He said so, to make sure the roll to vertical wrists happened.
Study the swing sequence.

I'd say he was a nearly perfect 4-barrel swinger.
I would change the two-foot balance, right foot balance and left foot balance, and the leg straightening to what we now know (Zenolink) as good biomechanics and keep the center of mass between the feet, not on top of them. It's the natural way the body wants to move.
On top of the feet you've lost all the ground forces you could have built up in the backswing and have to recreate them.

He did not spin the hips out before impact. They pause to transfer momentum to the shoulders to build upon. The hips hit the ground forces in the front foot. Whether Mike Austin did or did not do this, angle the left foot out about 30 degrees to receive those ground forces without rolling over to the outside.

So quit looking for something with which to throw it around the circle. It's the shoulders with the hands glued to the shoulders from the Top for a very long time.

The swing sequences show all this.
