Shawn -

I missed your post here.

I think the terms linear and rotational are best interpreted in the context of Jack's mechanical model of the swing which breaks it down into 1-CHP/connected/flail/double/compound pendulum and 2-handle torque, which are blended.

In the baseball power swing, the PARAMOUNT issue is timing which requires minimizing timing error by preventing deceleration before contact which in turn means that you do not disconnect from the CHP component prior to contact.

Torque needs to be applied in a manner that enhances rather than interferes with CHP.

Jack recognizes this as CHP and observing that the shoulders keep turning until contact

(aside: shoulders/scaps "bypassed" in terms of being an active part of the turning mechanism, passively turned in my opinion via unloading of a coiled torso between tilting shoulders - which are boostoing handle torque - and then more level turning hips since active turning of shoulders "rushes"/interrupts/degrades coil)

not pooping out before then reaccelerating.

Shoulders that primarily tilt rather than turn enhance torque and loading and ability to blend CHP and torque synergistically.
