Doesn't compute, unless I'm not understanding how the overpull estimate is stated. >> Greetings, Assume a 20 cent flat piano, everywhere. A SAT will have you pulling things 5 cents sharp as you go, actually increasing a little as your efforts affect the strings in front of you. So, let's say the final octave is 22 cents flat. Adding 5 cents to the C88 doesn't represent much sharpening. Musically, some tuners like the C to be far sharper than that anyway, and from a pitch raise standpoint, the difference is neglible to your next pass. I don't know of any commercially viable aural pitch raising techniques that would provide for C88 to be closer than this to its final position. Regards, Ed Foote RPT (All this problem can be avoided by not raising that last note past standard pitch.....but that means you don't want to raise the B7 either, then what to do about the Bb7, and pretty soon, we realize that there is no where to begin and we CAN'T raise the pitch at all!
