Charles, It's been my experience here on Long Island (I assume it's the same in like climes) that pianos which are well maintained drop most in the temperment octave area, an octave or two above the bass break. Left unserviced for an extended period, the pitch eventually drops all over, less in the bass and more in the extreme treble. This year the trend has been magnified by the unusually wet spring and summer followed by an extremely cold and dry winter. As far as floating the pitch, 8 or 10 cents above or below 440 is not inappropriate in most circumstances - concert tunings excluded.
