A435 or 440?

[David Nereson]

Curious how most techs are so adamant that it be right at 440,
yet when the question of floating pitch comes up, many are
content to let it be sharp in the summer (as much as 25 cents)
and flat in the winter (if 20 cents flat, it’d be at 435) so
they don’t have to do so much pitch raising and lowering all the
time.
