Hey, let's not dismiss those careful calculations - 
they do help the daredevils to assess the risks being
taken.  Notice how much the base jumpers check their
facts before a leap.

The calculations are quite correct, too.  For those with 
a distaste for school-stuff, the rule-of-thumb of 2% per 
grand increase in terminal velocity may be welcome and
sufficiently accurate.  1.7% if you have a calculator.
