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.
