Sorry to butt-in. But "Snap Release" is a Term Used to describe "how far along the straight-line delivery path when the Pulley begins or is initiated". It's not a #2 PP Swing. It's a #3 PP Swing. Driving Right Forearm. At the Very End of the Straight Line Delivery Path, when there is no more straight path to continue, the Right Forearm/Hands meet the Pulley. Then, the Right Forearm "Snaps" into the Pulley.

The #2 PP Swing (Wrist Cock) focuses on Wrist Cock and Uncock. This is the Swing used when you want to feel like the Left Arm is "Blasting" off the Chest. This Blast off the Chest initiates "Throw-Out" and CF sets in to Uncock the Left Wrist. It Doesn't get a "Snap" Release. With this Swing Type, you don't feel the Straight Line Delivery Path because the Right Forearm is Passive (Alignment aid only). Hence, Random Sweep Only when using the #2 PP (90% of Golfers).

BOTH, the Straight Line Delivery Path and "Left Arm Blast Off the Chest" are the "Hand Acceleration" Phase (of the downstroke acceleration sequence). Pulley, is Clubhead acceleration. Controlling when "Clubhead Acceleration" begins is directly controlled only when using the #3 PP to sense Inertia and Acceleration. It is only indirectly controlled when using a #2 PP Swing.

While a straight line delivery path can be useful as an intention, all hand paths are curved. Uncocking the LW by driving the right forearm will lead to early onset of uncocking in all but the few with extremely flexible wrists, and even then, is inferior to the cf snap release I'm talking about, because it induces forearm and wrist tension as well as forfeiting pivot power both resulting in slower shaft speed. If the hands get to the right thigh before the onset of uncocking with the shaft horizontal or above, random sweep can't happen, it's too late, and the inline condition will happen suddenly(snap) and most effectively, as long as the bent right arm is passive(no forearm slapping motion or firing right triceps) and the forearms and wrists are tension free.
