    I don't think I am qualified to define style requisites in terms of 
stretch.  I have found some venues that benifit from more attention than 
provided by a straight FAC.  The recording bass players are very sensitive to 
stretch, and studio pianos I keep the bottom end sharper than optimum.  This 
allows ensemble clarity, and the producers are very sensitive to the piano 
and bass hitting together, both in tempo and pitch.  
     For this, the SAT III's octave button is useful, and I put a -.2 in 
there for the first octave,  -.1 for the next two, and then zero it for the 
rest of the tuning,  I avoid problems.  This almost sounds clunky, but there 
is no noticible break in the octave widths, at least none that has attracted 
attention.  There is less overall resonance when the upper partials of the 
lower notes are sharp of the fundamentals farther up the scale, but this is 
not a problem in this venue. 

     About the jazz world, I am just learning, and hope to hear more about it 
a the convention.  In general, a lot of sharpness, ( stretched octaves) gives 
a buzzier sound to the thirds.  One of my lounge customers described it as 
having a lot of "churn", and he like it.  Jim Coleman's perfect fifths 
temperament is useful in this job. 
 
I've heard that your "C" number should *never*
>(well, hardly ever) be lower than you "A" number, and that raising your
>"C" number will give you additional stretch in the high treble. 

     Hmm,  raising it will sharpen your treble, but many of my tunings have 
the A higher than the F or C.  Dr. Al could tell you how the two values are 
balanced in the machine,  but I have found the FAC results to be spectacular 
with the big pianos,  way beyond the musicias' ability to detect 
irregularity.  If there is a request for more or less sharpness, the 
manipulation of the FAC numbers will allow  the machine to smoothly,(more or 
less) give you a "bent" tuning that fits your use. 
Others??
