Difference between Randon and Snap loading?

[Delaware Golf]

Just remember, everybody, that there is a difference between when the Shaft is loaded and how the Shaft is Loaded. In Pivot Strokes -- Hitting or Swinging -- the Shaft is Loaded by the Pivot. This is true whether the Player's intent is to Drive the Club through Impact (Hitting) or Drag it through Impact (Swinging).

When Hitting, the Hands stop at Top (Right Shoulder High and On Plane) and "resist the Backstroke Motion" (7-19-1) as the Hip Action initiates the Downstroke. When Swinging, the Hands typically proceed to the End (beyond the Top) and the Body Turn (Pivot) -- not the Hands -- "throws the Club against the Lag Pressure Point at The Top for Drag Loading" (7-19-3).

Then what is the difference between 3 barrel hitting and 4 barrel hitting?
