This would likely be just before the RH begins to rise (at least it does here in Mississippi around that time). If the piano had been tuned to A439 then, it would be closer to A440 now.<div>
<br></div><div>I would agree that a one-pass tuning might not have every note "spot on." However, one could get the piano in decent musical shape with a one-pass tuning ... even with numbers that you mention below. Since this is a school piano, and schools generally won't pay for a pitch correction, I'd do the best I could with a single pass.</div>
<div><br></div><div>My attempt would be stabilizing the entire middle section to A440 first. (By tuning all unisons there.) Then begin working on the treble, tuning slightly flat octaves, and tuning unisons as you go. By listening to your progress, it will become evident if you've chosen the right amount of "flatness" to your octaves. My first try would be tuning the treble so that the octave-fifth has a beat of 1-2 bps. This would be perhaps even a slightly flat double octave. But, it usually goes back up when it's that sharp, so you anticipate that.</div>
