Out-of-Tune at the piano store!

[Farrell]

I am curious also at why a new piano would go out of tune so very quickly.
It has really caught my attention that a poorly fitted pinblock, loose
pinblock screws, or loose plate screws could produce measureable instability
problems. But to clearly characterize the piano's out-of-tuneness, the
requested information was "how MUCH was it out of tune", i.e. please provide
a quantification of "flat" and "wavy" in beats/second or cents. To quote my
high school physics teacher whose words still echo in my ears: "Units,
units, units, where are your units. Your data is meaningless if you do not
indicate your units." (Those dudes @ NASA working on that recent mars probe
(the one that crashed because of a metric/english units mixup) should have
had MY physics teacher!)
