Interesting that he seems able to narrow down all
orchestras to a 1dB range
like that. Reminiscent of the way undergrads sometimes
write down a lab experiment result to as many
significant figures as their hand calculator displays -
regardless of having input figures only roughly
accurate. :-)

I've just flown back from the USA on a plane that was,
according to the "flight information" channel on the
in-flight entertainment screen, flying at a constant
height of 37,000 feet - or 11277m. (Actually, according
to my calculations, to the nearest metre, that should
have been 11278m). Or is it possible that the actual
height was 37,000 feet plus or minus quite a bit, and
that there was a spurious precision to the "11277"?

If you are worried about an airplane's altitude to the 5th digit, you
obviously need to find something else to do with your mind! ;-)

BTW, which part of the plane was the measurement centered at? ;-)
