Hmm..., your dates below start in October of 2002 and the next time you see the piano it drops predictably enough I suppose... but then ... what..... you have a poisoned tipped tuning hammer ? These pitches are before you start tuning I suppose... but where did you leave them ? 440 blank each time ? Assuming thats so... then from August of 2003 onwards the thang almost seems immune to RH changes. Actually... it almost looks like a fairly typical old beater with flat panel that you tuned for the first time in October 2002. You got any numbers that go farther back ? Cheers RicB /If one had access to an old WurliTzer grand with the split/wedged pins in a metal block, I'm sure you could set the pins so tight that they are the same as welded. Of course, then there might be other tuning stability factors involved. ;-} One I've serviced since 1984: 4'9" 1931 vintage 10/02 - 441Hz - 60% 2/03 - 438.1 - 32% 8/03 - 439.7 - 75% 2/04 - 439.3 - 34% 6/04 - 439.7 - 58% 1/05 - 439.7 - 32% NOT a scientific study, only anecdotal.
