Jack -

You have appropriately criticized how often "cues" can be nterpreted to promote linear disconnection such as "keeping the shoulder in there" , BUT, at the same time these same cues can be descriptions of desired "feel" of a god mlb swing.

Keeping the shoulder in there and not flying open and hitting against a firm front side are all descriptions of how upper body load/resistance creates "early batspeed" and the non freewheeling turn and ability to control the swing by hands that are torquing the handle. The handle torque then tilt of the shoulders provides upper body resistance to power a quick adjustable swing.

I think the "x-factor"/"x-factor stretch" description of the kinetic link with expected "efficient speed gains" as in golf is a good way to understand what is happening here based on quantitative motionanalysis measurements such as with Zig/s technology.
