Elliskit,
I think the following from your post above is an excellent point!

Quote: "Here is a thought that I cannot find stated explicitly in the book, but I think it is valid and relevant to this discussion: Increasing Accumulator #3 enables greater handspeed because it allows a smaller radius (less effective mass) for the clubhead"...UnQuote

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!
