[CAUT] large and rapid humidity changes!

I agree with this sentiment Fred. Its doable and it would help an 
enourmous amount. When we built our new pipe organ we installed a 
climate system that set its sights on this range. We know ideally we 
should have a more narrow window... but this was far far better then 
doing nothing... and it was a very affordable and easy to maintain system.

   A seasonal variance, carefully controlled, of 30-60% would be a
   dream come true for probably most
   of us, and would cost a lot less to run than a 35-45% year round system.
