Interesting. Exactly the concerns I have over electronic 
devices. I haven't yet run across anything indicating such, 
but I would be interested if anyone has found any evidence to 
the effect that the response rate or amplitude of a piece of 
wood moving unrestrained through repeated naturally occurring 
humidity ranges changes over time.

Yup, as I suggested, for the unconvinced cautious.

Very likely, but that's why you give it a day at equilibrium 
at a relatively low temperature for the panel to catch up, 
rather than cranking the temperature up to 400° until the gage 
reaches a certain point, and yanking the panel out.
