Bill,

I wanted to tell that the 'reconciliation 'of the twelve's, doubles (and 17
this eventually) , is a very powerful tool for tuning fast and after
different tuners.
I was doing that yet sometime without knowing, and your description of the
process in EBVT open a door in my brain (that is why there is so much air
going inside now).

Just wanted to thank you about that.

    At least for me, it would simplify the puzzle if you could list one
complete
    octave (F3-F4) using the same partial for the entire octave.  F-F is
good,
    because that would be a pure 5th, giving an untempered octave, which
allows
    for the octave stretch information when calculating for the offsets.


  Sorry, I can't really do that.  The info I provided is directly from my
SAT.  I always program the SAT to have the 3rd, 4th and 5th octaves read on
octave 5.  This means that Octave 3 will be read on the 4th partial, Octave
4 on the 2nd partial and Octave 5 on the fundamental.  I have my reasons for
doing it this way but unfortunately, it is not compatible with the FAC
program's partial selection.

  The amount of stretch I put in the octave is deliberately not the same
from note to note.  It depends on how much tempering there is in the
corresponding 5th.  That is the main reason for the futility behind trying
to find the usual correction figures for the EBVT.  I simply don't tune my
octaves according to a smooth curve calculation.

  I wasted about 1/2 hour yesterday fooling around with this and got nowhere
(as usual).  I did notice however that the piano, tuned the way I do, had
very small differences sharp, flat or about the same from the calculated FAC
program.  These small differences allow my tuning to be acceptable by itself
and to be compatible with other instruments, even fixed pitch instruments in
ET.  It is a good example of how very small deviations can and do make a
difference when they are applied purposefully rather than being errors made
at random.
