I think a lot of the reasons for the alleged pitch drop has to do with initial tunings when the piano is new. Often the piano isn't brought up to pitch with the store tunings. Then if it has any subsequent if often tuned again where it is. Then it may go through years without tuning and finally when Sir Gawain the tuner comes to the rescue he finds the piano way below pitch and then begins to wonder why do pianos drop in pitch so much? ;-] In California finding a piano at pitch after many years is not that uncommon. Finding a piano above pitch is also not uncommon although it probably was tuned above pitch...
