post pitch-raise creep?

[Cy Shuster]

I've been chicken to try that big an overpull percent on the monochords, for 
fear of breaking them.

In the TuneLab Pro documentation, Robert Scott recommends 12% for the bass 
bridge and 30% elsewhere, for small to moderate pitch raises.  For better 
results (tuning unisons as you go, bass to treble):

        bass bridge            12%
        tenor bridge to G5   29%
        G5 to G6                29% increasing to 37%
        G6 to C8                37% decreasing to 14%  (tension gets high up 
there)

TuneLab's ability to measure each string and calculate a precise, individual 
overpull percentage in realtime is one of its best features, I think.
