stability of pitch raises

[Kevin E. Ramsey]

    Don; I just try to do the most stable tuning possible, and hope that
it's lasts as long as possible.  I know it's going to start going out of
tune the next time the customer touches the thermostat, but if I lied awake
at nights worrying about the inevitable, I wouldn't be doing anyone any
good. Physics, after all.....
