Ed, The manual that came with my new SAT III about 2-1/2 years ago is quite well-written, IMO. As a BRAND-new tuner at the time, an awful lot of it was way over my head.  As a tuner now with 2-1/2 years experience, some of it is still over my head, but I do comprehend at least all the concepts he presents. The DO stretch is probably what your ear will tell you to vary. You can also change the "F", the "A", or the "C" setting on the fly to stretch just the part of the piano determined by that reading (the manual tells you which parts of the tuning are determined by which reading). I also own an RCT. The manual for that, well, there's NO comparison to the SAT III's manual.

I wonder if anyone can shed some light on how the tuner overides SAT III calculations. I know that after the FAC is programmed and SAT spits out its appropriate tuning some changes can be made right off the bat by checking A2,A3, and A4 octaves. And I know the double octave feature may come in handy at this point, as well. Here's my question: say you're happy with things from the outset, but as you go further into the SAT's tuning you find some notes that you know can be better placed, how do you tell the SAT to adjust on the fly? It seems to me that the interconnectedness of a tuning would make it difficult to suddenly disagree with what the SAT is telling you about a few particular sour notes without screwing with the notes you've already tuned, or are about to tune. The core of my question is how does the tuner be the "master" of the SAT III throughout a tuning? Any thoughts would be appreciated.
