Hi Del,
No arguments on your points at all. How ever the rate of feel, (
the amount of follow) especially from new spriny felt has a big impact.
The number of pianos that I have seen with little or no follow is too great
to count.

Add to this correct node points. Just raising or lowering the damper
position a few mm at times will do what none of the other solutions will
cure. One of the reasons I favour triple dampers.
Your point about mass loading the damper head is well taken. I think the
Yamaha U1 and U3 models are good examples of well designed damper systems
in this respect. Very substantial maple blocks and heads.
