The first thing about Pete's swing that jumps out at me is his beautiful Longitudinal Acceleration , Drag Loading, straight line Delivery (Hand) Path. But then in Release Id say he throws the clubhead past the Hands using a Pause Minor Basic Stroke 10-3-J. Intentional Quitting and Throwaway. He's swinging the clubhead as opposed to the Hands in other words, intentionally.
The other way of saying this is "the kid's got a great set of Hands".

10-19-C....Start the Club down as though it were being drawn from a quiver like an arrow – feathered end first. Maintain this motion until the Release switches ends. This is possible only if, and for as long as, Inertia can hold the Clubhead inside the arc of the Hands or hold to a Line Delivery Path (2-L). Centrifugal Force will set in when the Clubhead crosses to the outside and it will begin to pull into its own incidental orbit per 2-P and 2-K#5. Then further acceleration can be applied only at Pressure Points #1 to support the Pull on the Clubshaft – especially for Short Shot Power.
