[CAUT] Unison Tuning

[Don]

Hi all,

Here are some limits of resolution for Reyburn Cyber tuner, and some raw
data for someone to crunch.

All measurements taken at A4 measuring at A5 in pitch correction mode with
maximum spinner speed.  The piano was a 42" Balwin that had not been tuned
for two years (pitch correction of 1.85 cents at A4)

All three wires sounding.
