I think I am beginning to understand the effect of the #3 accumulator angle thanks to Elliskit's post.

There is rotation of the primary lever assembly about the left shoulder and, when a #3 accumulator angle is employed, rotation of the secondary lever assembly about PP#3.

If the #3 angle is zero there is no clubhead rotation about PP#3 - only clubface rotation.

If the angle is large at release, the effective mass of the clubhead is increased and angular velocity is decreased. This extra effective mass will tend to slow down the hands and a greater lag pressure will be felt on PP#3.

If the angle is small at release, the angular velocity is increased and the effective clubhead mass and swing radius is decreased. This will lessen the tendency of the hands to decelerate.

Does this makes sense?

Cheers,
