Your numbers are quite different from Sanderson's, yet you say it works =
and I do not doubt what you say. So what is going on here? Why would =
both work? What factors here are critical and which are not critical?

New question, since you have the SATIII with the built in program for =
the raise, why not just use that? What do you get when you do, compared =
to hand calculations like yours or the good doctor's?

  Kevin,
  If the bass is about 30 cents flat I want to raise the note about =
three cents sharp ( about 10% ) of pitch. So with a SATlll that raises =
the pitch 25%  that would result in too much over pull for me so I will =
set the over pull for 12 cents and roll the program into the machine.
  I take only one measurement at A2 to arrive at my over pull. Works =
very well for me.
  I use the 25% in the tenor and about C4 the 30% to the top then =
retune.
  On pianos 25% or less flat or sharp I use the Verituner 100 and its =
10% bass, 30% tenor,
  and 36% treble and retune.

        Here's another little brain saver:  What if you're pitch raising =
a piano and want to do a 20% overpull in the bass, and it's, say, 28 =
cent's flat. (let's see, one fifth of twenty eight would be ......... =
ah........ ah........) =20

        Take 28, and double it for 56. Move the decimal point over to =
the left one place.=20

         5.6 is 1/20th of 28.=20

        At least, that's how I do it.=20
