tough enough

[Don]

Hi Bob,

3 or 4 cents flat may often result in 1 or more cents flat at A4 unless
some overcompensation is used. Even just 2 cents may need a bit of "fudge"
to the sharp side to end up "dead on" A440. The "sharp/flat" of the test
piano is needful unfortunately, even though it is not "real world". 

And in my real world a piano that is 3 or 4 cents out of tune is the
exception unless the instrument is equipped with a DamppChaser system with
a back or bottom cover.

average piano in the field.  That's not flat enough to skew the accuracy of
the test by reason of instability - especially since we are moving only
center strings.
