    Well, in the applications I have used the CA3280, it wouldn't really
matter to me in that any added offset would be fixed, since once I set
the glide rate, I have generally not changed it.  This should be a
pretty simple measurement.  I will put a sticky note on calculator so
when I get home tonight (about 12 hours from now), I will remember to
make the measurement.  I will let you all know then...
