I don't do a lot of tuning, but when I was using a sight-o-tuner I would set it to 11 cents sharp and tune A440, then tune all "a"'s by ear quickly. Then set the sot to 10 cents sharp and tune all a#'s. Continue this sequence to G# at 0 cents. This has worked well for me for pianos 30-50 cents sharp. Now that I have a sat11 I still use the same procedure since I pitch raise so seldom. I like the fact that the pressure is being appllied across the scale in a uniform procedure. I suppose I should take the time to try the sat11 pitch raise program, but this old dog likes old tricks.
