Hi Conrad,
                The numbers would be good IF you had an absolutely stable
bridge and sound board, I seriously doubt that you could relate it to cents
because of this factor. 
I agree with all your points with regards to predictibility of coefficients
to metals, since heat transfer is also and rate of expansion is
predictable, but trying to predict lumber??????? in tems of cents, now that
is a challenge.
I'm smiling not picking.
