Of course, "smaller radius" could have a lot of different perspectives- so if not obvious to someone- we're talking about Conversation of Angular Momentum- and having the center of gravity of the lever assemblies closer to the center of rotation- i.e. the pivot, just like the speed skater- therefore allowing a higher hand speed or put another way a faster rotation.

Although, I'm not relating it to any of the previous posts- as you stated- it's a different perspective than Homer was referring to- but your point is a separate and valid perspective, and does have it's own relevance to the topic.

Original thinking should be rewarded- nice work!:)

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?
