You can only keep the right arm and the clubshaft at the same rpm if you zero accumulators #2 & #3. If you freeze accumulator #2 in a level position you can have a very even and gradual overtaking.

If you add some Accumulator #2 action to your stroke, things aren't so simple anymore. And that's why we need to manipulate CF, sustain lag pressure etc to prevent the overtaking before impact.

The full golf stroke is deemed to collapse sooner or later. But skilled players know how to keep it together until the ball is gone.
