Very interesting question--

[David Nereson]

    I've encountered maybe two pianos over 30 years that were
about a minor third flat (about 300 cents), and they had come
from humid climates to a dry one, so the soundboard lost much
crown.  I've found individual strings much flatter, of course,
due to loose tuning pins.

  I wonder what the limit is as to how far flat a piano will go
if it is never tuned. Let's say a piano was built in 1900, tuned
many times in the factory until the strings were stretched out
and the tune stabilized.
  If it were never tuned after that, would it reach a point,
let's say, in the 1960's, 70's, or 80's where it would not go
flat any more? And how flat would it end up being -- 150 cents?
200 cents? I'm curious because I've seen many old uprights that
were about 150 cents flat, and I wondered if they were ever
tuned over their 100 year lifetime.
