You have to factor in temperature as well.  EMC will be a function of
temperature *and* relative humidity.

I've noticed something curious over the last couple of weeks on many of 
my institutional tunings.  The pianos are starting out a little flatter
than would normally be expected considering the snapshot of RH that I
record.

Here's an example from a Yam p22 in the college choir room

Tuned early sept 60%RH
late sept 49%RH - ave 5cents low
early dec 29%RH - ave 20 cents low

all of the above reflects what I normally see.

today 31% RH - ave 10 cents low...

I guess a data-logger might provide more info.  

Anyone with educated guesses???
