I did simplify it when I said hands speed vs clubhead speed. It's actually hands speed ^2 versus club head speeed ^2.

So even if clubhead speed were twice the hands speed throughout, the MOI center would move as both speeds increased.

But even though the RF flying wedge is kept intact, accumulator #2 certainly, and I also believe accumulator #3, will change the relationship between the two speeds. And it is also a fact that the hands will slow down while accumulator #2 is releasing.
