    OK, now, a 6/3 octave has the sixth partial of the lower note being =
compared to the 3rd partial of the upper note.
    Fourth partial of lower note to fundamental of upper note would be =
the correct test for a double octave.
    The fifth has a 3/2 relationship, but it doubles again an octave =
higher at 6/4. I can only assume that the tunelab setting of 6/4 in the =
bass would be to quiet that faster beating interval down by adding =
stretch to it.=20
    An octave and a fifth is a twelfth, and it's a 3/1 partial =
relationship. Usually used to add stretch in a machine setting. That =
might help you get that bass down there, although I haven't really =
checked that out in my own tuning too much.

"Sorry, I am confused, you say use the 6:3 octave in the bass and using =
your
sample Steinway D file this give a -2.44 cents at A0. To me that is too =
high
and if I say I want to have pure double octaves in the bass and go on to =
4:1
double octave in the bass, I wind up with a reading of +1.77 cents on =
A0.
If I use 3:2 fifths it is -7.5 cents on A0 and using 6:4 fifth, it is =
-10.6
cents on A0."

    I wouldn't tune any pure double octaves in the bass. Leaves it much =
too sharp for my taste, especially on a "D".
Try 6/3 octaves + 1cent. When you get to the single strings, go to 8/4 =
octaves. Use your ear. Play with that 6/4 setting, -10 to -12 cents =
sounds closest to a ballpark guess to me.
