To Tony Caught:

You had one item backwards in your description of the 6-3 Bass
octaves. It is the 6th partial of the lower note and the 
3rd partial of the upper note.

If you end up with a -2 cents on the 6th partial of A0, 
your fundamental of A0 is probably around -10 or so. This 
is not too bad for that area of the piano on a low 
inharmonicity piano.

In TunelabPro, us "T" to dink around with the graph. To make 
it lower in the Bass upper screen  use the control key "h"
described in the help screens. You may also raise the high 
treble by using the control key "o". If you go too far, 
you can use the "y" Key in the Bass to raise it back up a 
little, or use the "l" key to drop it back down a little.
All of this adjusting is according to your personal 
preference. You can view the graphs in either cents or beats
width. Use c for cents and b for beats.

PS On the subject of short duration in the treble, If there 
   is no possibility of putting on new hammers where you can
   do some deep shoulder needling, you can give the 
   impression of a little more duration by very carefully 
   tuning one string of the unison to get the bare start 
   of a beat going. This is very tricky, but may get you 
   out of a bind on a note or two. This is not a solution
   to the problem, but only a temporary fix when there is no
   other possibility.
