Perhaps a more relevant example to this thread would be that other
inverse square law of motion - the walking speed of a group of people

is inversely proportional to the square of the number of people in
it. :-)

I'm sure Mr Jelf has his techniques!

He's not only heard of it, he's done a lot of practical research on the
