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.
