fac question

[Jim Coleman, Sr.]

HI Wim:

My understanding about FAC numbers changing is that during a pitch raise
the string takes a different bend through the Agraffe for a while which
causes the inharmonicity to be different. Eventually when the string
levels out, it will be more dependable at to the inharmonicity stability.

However, I think this is rather insignificant in many cases. The additional
loading of the soundboard probably has something to do with the changes
too.
