Ron,
I'm curious what happens to the tuning after you close them back up? I have 
a situation in a small college teaching studio where the AC is uncontrolled. 
It will usually be 63 degrees in August and somewhere around 80% RH. Pitch 
swings were wild, so I installed a dehumidifier only system.  I'm thinking 
of carrying a space heater with me next time to warm the room some before I 
open up the 2 Yamaha P22s. I figure if I let the strings cool down to the 
room temp, then tune them, then close the piano back up, the tuning will go 
haywire in 20 minutes.
