Actually the three was to give a tie breaking 2 to 1 vote as to which was
correct. This logic followed into the early maned space craft. They all
carried three computers, even of different manufactures so that a design
flaw would not skew the vote in favor of the wrong answer.

You can take this logic even further and end up with what is now the
California Governors Off Season Race. No one will have the correct answer
as there will not be a statistically valid vote with some 200 candidates at
last count running. And we want to make Iraq a democracy? Enough of that.

A good standard it the key to any measurement. A good set of accurate
1-2-3 blocks is a great start.

By the way, did you see the news story on the old missile silos for
sale. One of the uses was for highly controlled temperature for precession
machining. Ahh, to have a machine that a couple degrees temperature could
make a noticeable difference. That is other than my digital readout on my
faceting machine for which I had to make a chart showing room temperature
and correction for the actual angle.
