On larger pianos we figure 10% of the amount flat on the bass bridge for
over-pull. If I encounter something extreme, like 70 cents, I plan
on a three pass pitch raise. The first time I pull up to pitch, the
second I over-pull and the third is a thorough fine tuning. I do
this in part to avoid breakage and because measuring large over-pulls is
not encouraged on the VT. The limit is about 60 cents (or 6 cents
over-pull in this case) for the VT.<br><br>
