I just find this amusing

The straightening of the right wrist doesn't happen until much farther past impact than he demos, in most every good player. It happens too soon for him, because of pivot stall, which he prescribes in order to "snap the kinetic chain", which is nonsense. He has actually stated that a complete DS pivot all the way to anatomical limits is "crazy".

As for yanking up through impact - that's a misinterpretation of the Miura paper on "Parametric Acceleration", which was written 11 yrs ago, and was presented as a "new" revelation by a certain "explosive" GSED, who proceeded to misrepresent and discredit the concept of Aiming Point, to help sell his toxic koolaid.
