Hi Joe. I just re-read through your article (yes it was Dec. '99) and I have the same question I had back in '99. How does your SAT program differ significantly from doing an FAC and then pitch raising, or chosing a canned program for a similar piano and going at it. This I ask beyond your good advice regarding to do a pass without overpull prior to using the overpull when there is any doubt regarding string strength. It seems to me you will always be better off using the overpull judiciously in the various sections of the piano as so many are perhaps only a bit flat in the bass, moderately flat in tenor, and more flate in treble.....or whatever (of course always being wary to not use too much overpull so as to be breaking or overstressing strings - the most I will ever do is about 15 to 20 cents overpull, i.e. correcting a 50 to 75 cent flat pitch). How does your program improve over measuring FAC/canned-similar and using the pitch correction properly?
