The #2 accumulator is the true velocity accumulator. I believe this to be a critical element of understanding about #2 release. Maybe the most important element.
#2 release can change #3 rhythm and must be planned from the top??

This is confusing. Do you mean that the #2 release can disrupt the #3 release?

The #3 accumulator relies on the Bent AND Level Right Wrist, the Pivot and the Right Elbow Action.

The #2 accumulator is very dependent on the #4 accumulator release which relies on the Pivot. Replace your Left Arm, Hand and Wrist with a Rope. Take the Rope to the Top of your Swing with Extensor Action. Use Downstroke Shoulder Acceleration to Blast the Rope off the Chest. Where is the Left Wrist Cock? Think about it for a minute and take your best guess.

Hitting a 7 iron 190 yards is not a strength issue. It's technique.
