[pianotech] Was high and outside now silent pitch lowering

[Terry Farrell]

I find it curious how folks find differing overpull percentages working for pitch raises. For me, I've settled on 16% in the bass, 28% in the tenor and 38% in the treble. Seems to work just about right on most any piano. I use the Sanderson method: A0 to C88, unisons as you go.
