[pianotech] Measuring Action Ratios

[David Love]

I guess we all use what works for us.  No harm in that until we try and
communicate with each other.  Then it's like we are speaking a different
language. 

Thus, it's not all that important (to me) that the hammer travel/key dip
ratio doesn't necessarily jive with my lever measuring system, it's more of
a curiosity.  I rely more on my lever measuring system (which is, of course,
not *my* system, I did get that system from others who also use it reliably)
to predict outcomes and targets and so far it does a very dependable job.  

Y(or others')MMV, apparently.

Or both are wrong, or as we're told every now and then, not wrong, just
different. Yep, doesn't make sense. Last time this came around, I posted a
measurement system that produced the same ratio as direct measurement on my
action model, but bore no resemblance to any accepted system. This ought to
be easier. We're apparently looking at something wrong.
