What matters most?

[Mark Davidson]

I recant.

Here is a simple counterexample that shows you can have
same SWR and different inertial "feel".

Start with some SWR, say 6.0.

Move capstan closer to balance rail.  This will reduce motion
of wippen and hammer.

Now move knuckle closer to hammer center until SWR is 6.0 again.

This leaves the wippen moving with less speed and distance
than when you started.  Key and hammer move the same as when
you started.  There is less total energy required because
wippen does not accelerate as much.  In other words, you
can change the wippen speed independently of the hammer and key
speed.

Whether you can actually feel it is another question...
