Being one who started tuning back in the Aural Era, I smile at a resolution of 0.1¢, which at A440, would mean having to wait 40 seconds for a single 1 Hz beat rate.
(Please do correct my math. I figure that an error of 1.0¢ between two pitches would produce a beat rate period of 4 seconds. A440 and A441 have a 1 sec. period. Of course, moving these mismatched pitches downwards in frequency would of course speed up: at an octave lower, you'd only have to wait 20 seconds for a beat rate cause by a 0.1¢ mismatch.)
And of course, back in th'day, if we were left with only our ears to detect such small errors, the musicians were in the same boat.
I remember the late, great Dean of Piano Techs in the Northeast (north of NYC), Frank Hansen explaining to the N.H. Chapter, 40 years ago, how he set A440 for the Boston Symphony Orchestra and Tanglewood. 1.) set C4 at a 523.4 C-fork, 2.) temper F3 for a 5th he was used to, and temper A3 for a M#d he was used to. That was his A440, with only an occasional, specious complaint.
As far as music departments and school system with their start-o-school tunings (current pitch at 445-6), those tunings get floated @ A442 (8¢). Much beyond that and band instruments pitched at A440 find their inherent intonation warping badly (which is not to say that a symphony wind player won't get disturbed at 4¢ deviation). At the end of the Fall semester (and for the practice room pianos, the JAN tunings), they are ready for a spot-on (<G>) A440 tuning.

Greetings,
While my obsessive/compulsive nature, (an essential ingredient in good piano work) hides in mortification and chagrin, my practical, compromising self is drawn to champion a loose embrace of the imprecise.
Adherence to exact A440, (which, of necessity, requires a numerical definition of "exact") may be utile as a narrow gate in our clinical testing for admission to the ranks of RPT, insurance while in the orchestra pit, and perhaps to the neurotic record producer scrambling for excuses when session players are having some trouble with their "tooning". However, the pitch is more useful for us making a living when it functions more as a guide rather than a specific point. The case of environment is one major example. Allowing pianos to rise and fall with the seasons is far more beneficial to their stability and our cost/benefit results than forcing the tension one way or another because it is not "exact". A440 can then be a legitimate pivot point around which the piano swings rather than a fixed target at an exact moment.
Ancient strings may urge for more slack, the tragically continental violinist may see A 443 as the mark of sophistication, but for the most part, the tech may do best by allowing the piano's use, history, and environment to form the 'standard' to which it is taken.

I am a strong believer in 'floating' pitch seasonally for non essential 440 usage , ie the majority of home usage , some schools etc especially in New England , for some of these situations I would note the floated pitch on a Post It and tuck it away so I could reference it next time……ok 440 disciples have at it!.

If 440 is demanded...close. If it is not demanded, let it float as you see fit for minimal tension alteration and maximum stability.

Larry,
Your comment sort of changes the direction of this thread so I'll ask: If we claim to tune to A440, how close to A440 do we need to get? 10 cents? 1 cent? 0.1? Just float the pitch wherever you find it?

I understand the problem of A443. You want absolute accuracy at A440. Will that last overnight? The next day when the humidity changes? A440 is a shibboleth which we spent too much time perusing.

Put a fork in your pocket for a few minutes and then check the pitch. It will probably be lower. Your forks may be exactly 440°….at the temperature they were manufactured at.
Whatever the case, easily adjusted.

Hello!
I recently purchased two tuning forks from two different manufacturers. Both A440.
One is steel. One is aluminum. Both labeled A440. When checked against Tunelab, one is exactly 443 Hz and the other is 443.6 Hz. Both at 20°C.
Tunelab is calibrated and when checked against YouTube videos producing A440, it reads 0.0 Hz. I have a C 523.3 fork I've had since the 70s. It reads right on at C5.
Has anyone ever experienced this before? I'm at a loss to explain two forks from two different manufacturers reading 443 while stamped 440. There must be something that I don't understand.
Thanks!
Cary
