humidity and unisons

[Newton Hunt]

Hi Fred,

My commiseration.  I remember those days.  15% in winter and
85% in summer.  Movement as far as 100 cents season to
season.  What a pain with 145 pianos and being the only one.

Still back to the original post about the no pin block
piano;  I am still puzzling over the dynamics of your
observations.  How DOES that work?
