Hi Mike.
Those RH numbers look fairly similar to what we operate with over her.
My usual is to tune at A 442 in the fall and allow the pitch to drop to
440 during the winter but no lower. This is on pianos I tune for the two
University level schools in town and I am on each piano 4-5 times a
year. For a regular private job I dont see much point in floating
pitch... grin it float quite naturally enough on its own during the
average of 3-5 years in between the tunings most folks give their
pianos. I use a fixed pitch for concert and recording work as well, or
any teacher who requests it for that matter. I have one teacher who
wants 438 all the time because she plays Recorders of various sorts.
Floating pitch is not really all that time consuming for a single
isolated tuning IMB. But if you are visiting a piano 3-4 times a year
and have very good tuning technique it can save you some time in a
climate like the one you mention below.

List,
I need to go back through the archives and see where all the
proponents of floating live and work. Surely not in the temperate
zones of North America. Today I tuned a Yamaha P22 at the local
elementary school. It was last tuned in March, to A=440 at about
38%RH. Piano pitch at 68% RH today was: A0 +0, A1 +3, A2 +5, A3
+18, A4 +12, A5 +24, A6 + 35, A7 +20. No matter where I decide to
set the pitch of this piano, it's going to require a pitch
correction. Floating wouldn't save me any time or effort, nor would
it improve the stability of the piano. This is the norm for the
upper midwest, and I suspect for much of the country. Floating
might work on the coast or in the desert, but not here.
Mike
