Three barrel versus four barrel hitting

[Jeff]

Thanks for replying and indicating that even a single barrel hitting action drives the left arm. Could you please also provide your definitional understanding of the differences between a triple barrel versus four barrel hitting action.

Usually, If the Right Shoulder is doing work (any action) as opposed to not doing any work (just motion).

You are apparently implying that if the right shoulder is doing work, that it turns a three barrel hitting action into a four barrel hitting action. However, doesn't that work have to be defined in terms of further PA recruitment/involvement in the hitting action - turning a 1:2:3 pattern into a 4:1:2:3 pattern. Are you saying the right shoulder's active downplane movement releases PA#4 via a pivot-action and that PA#1 then becomes operant?

Jeff,

Cannot translate the last word to my language.

But,

The right shoulder can either be active or passive during startdown.

It will contribute with either action or motion.
