SAT III Stretch Question

[Farrell]

Is there something wrong with my SAT I, or am I doing something wrong
because I get the same tuning with both machines using 8.0, 7.0, & 6.0 for
FAC. Why do some people get one result, and others get something else.
Please enlighten me!

e.g. FAC     8.0     7.0     6.0

SAT    A0 = -13.7
SATlll  A0 = -13.

SAT    C8 = +33.8
SATlll  C8 = +33.8
