tuning question

Interesting technique. I've wandered if pianos that go through pitch raises
as much as this one actually fall in pitch because they were flat before, or
they drift flat (or sharp) because of weather changes. I do a fair amount of
store work and find that pitch raised pianos seem to stay until they are
sold and moved or there is a shift in humidity that causes the whole
inventory to go out. I occasionally have a piano or two in my shop ready for
sale and the tunings stay after pitch raises. Yet I hear others say they
need to follow up a pitch raise in a month or two for another tuning. Around
this area, a tuning will usually drift do to weather/humidity changes in
that amount of time. Maybe some one on the list knows if this has ever been
studied under a controlled environment. BTW I live in the White Water River
area of SE Minnesota.
