David, I agree with you about Virgil's method. Whenever I tune (in ET)
that way, I end up with nearly pure 5ths and very nearly to pure 12ths.
All the octaves are pure sounding when used in any combination.

There is something about it that allows you to tap into the hidden power
of that individual piano. I notice it EVERY time, whether it's a 9'
Steinway or Yamaha U1 - it is a different and better sounding piano.

For me, it took a fair amount of listening and practicing to say, "Yes,
I can now hear what is there." But it was certainly worth it.

Have you noticed that false beats in the treble are greatly minimized
when tuning this way?
