 It's pretty ancient, mostly rule-of-thumb stuff guided by some very
primitive data collection equipment.  Most of the formulae are useless
and the rest is suspect.  However, it remains in print due to the fancy
title and the fact it's still the only book around that even addresses
the matter, albeit poorly.
