Too many questions ... not sure how to answer them all right
now. I'll have to think about it more.
But here's an off-the-cuff response.
You had a post many years ago about how some pianos have a
"razor's edge tolerance" (or something like that) of where you
can set the string and have a beatless unison, and other's have
a "range" (a very thick razor blade with a "bull nose" edge
rather than the point of a 'V') within which they sound
beatless, or very close to beatless. Well, the ones with only a
razor's edge tolerance take longer to tune. You can't park the
car "anywhere in the driveway;" it's got to be on an exact spot.
Some pianos I tune every 3 months still take 1 1/2 or even 2
hours to tune sometimes. I don't know why. They're just
stubborn. There are others that only get tuned every couple
years, or even every five years or more, yet they stay right on
A=440. Some of those take 45 minutes to tune; others 2 hours.
The ones that take 2 hours are probably only 10% of the total
pianos tuned. And same with the ones that only take 45 minutes
(except in the schools, which don't always get a super-precise
tuning).
But in general, after I do a pitch raise, the final tuning
goes quicker, I guess because it gets it closer to the final
"target" than a tuning on a piano whose A49 is at 440, but maybe
the tenor is sharp or the bass is flat or whatever.
