Stupefying Pitch Volatility

I'm just curious what others do in these situations - not so much from a =
business standpoint, but rather from a technical standpoint. You had at =
least one note at +41 cents, and you ended up with the whole piano at =
about +24 cents. I take it the +24 cents level was close to an average =
deviation from standard pitch - so as to make your pitch adjustments =
minimal? Let's assume here your situation was what we all commonly run =
into: bass was about +10 cents, tenor about +41 cents, treble around +30 =
cents, and high treble somewhere in the +15 cents neighborhood. I would =
take a piano like that and shoot for a final pitch of +24 cents. You did =
two passes. Did you calculate/estimate pitch offsets during your first =
pass targeting a final pitch of +24 cents? And then was your last pass =
started with everything no more than 2 cents sharp or flat? Or how =
did/would you go about it?

I find that often these irregular pitch deviations can be quite =
challenging to hit your target pitch accurately.

  More of the same:  Today I tuned an 1899 Shiller upright, all =
original, even the bridal straps but in good shape.  It was a 3/4 plate, =
open faced pinblock design.  It is a *fixture* in this old house on the =
*organic, whole earth* side of town where there is no air conditioning =
and only a few blocks from the lake.=20

  Air conditioning or not, this is the time of year where temperatures =
are moderate, there is lots of rain and windows are open all day and =
left slightly open at night.  When the temperature goes down at night, =
the air quickly reaches its dewpoint.  Areas of fog (100% humidity) are =
common.  This is unfortunate because people want to use their pianos and =
want them tuned but it will only be a matter of weeks until sharply =
colder weather comes on, the heat goes on and 60% indoor humidity =
plummits to 30%.=20

  With an admirable record of service, the old Shiller upright's A4 =
stood on September 27th at +41 cents.  I mercifully evened out the pitch =
in a 2 pass tuning at +24 cents.  No, I didn't *fully inform* the =
customers who asked me to leave the bill, they were going for a bicycle =
ride around the lake.  I left the bill which charged for "Piano Tuning", =
my usual, going rate which is the highest in the area.  I didn't look to =
see if the plate was cracked although I didn't see any cracks in the =
plate when I adjusted the damper pedal.=20
