I agree. We were both frustrated that we couldn't understand
each other, in both cases, but it turns out that we were
thinking basically the same thing all along.

Sure, these are all good. But I was thinking along the
lines of, say, an axis representing a meantone generator,
such as (3/2)/((81/80)^(1/4)) , for example.

This is why, a few months back, I was so interested in
Regener's work. It seems to be along these lines...
transformations of ratio-space.

Well that, of course, would be the _right_ way to plot meantone
tunings. Which is what I was trying to tell you while grudgingly
figuring out for you how to plot meantone on the usual (3,5) axes
using fractional exponents.
