    Jon, As common practice, I will do a pitch correction any time the =
piano is more than one beat per second ( four cents) off of A440.=20
    It's really quicker than going back and checking, and going back, =
and going back, and then worrying.  So most of my tunings are two pass =
tunings, and I can do two passes as quickly as one where I'm agonizing =
over it.=20
    The exception to this rule would be something like a school piano in =
an uncontrolled environment where you just know that it's going to be =
sharp in Summer, and flat in Winter. I don't really think that it's good =
to be yanking them all over the place each time if they're only in a =
practice room. Still, same thing, two passes, because the bass won't be =
the same as the treble and tenor anyway. But there, I can usually do =
just one pass in the bass, or wherever........
    Gotta go, the monsoons just got here, and I've gotta go look at all =
that rain coming down.......

    I'm trying to understand what you are saying here Jon. Are you =
saying that if the piano is more than 8 cents flat (or sharp) you should =
first do a pitch raise, and then do a separate tuning immediately after =
(or later in the day for some reason?)? Please differentiate between =
tuning and pitch raise and how many passes you might commonly do. If a =
piano is 5 cents flat do you commonly only do one pass, raising the =
pitch 5 cents while tuning? Thanks.

  Wait, 8 cents is two beats.  I should have said 16 cents or 4 beats =
per second.

  A piano within 4 beats (~16 cents) can be left with an appreciable =
tuning for general use with one pass.
  A little beyond that maybe just a pass over the treble half a second =
time. It all depends on the situation.

  Concert work, 2 beats (8 cents) needs a pitch raise and tuning. That's =
where I went wrong.

  Lowering pitch is another thing altogether, more difficult. I'd rather =
raise 4 pianos than lower one.
