[pianotech] One Pass Pitch Raise

[David Nereson]

    For me, the pitch raise is almost always one pass, but then 
I still have to start over and tune the piano.  If it was around 
a half-step or more flat, that might involve a two- or three- 
pass pitch raise.  I don't attempt a one-pass pitch raise AND 
tuning unless it's just a few cents, because it usually won't 
hold the first time through.
