George sometimes just needs to be publicly wrong.  I appologize to all the
beginners who have not yet learned to tune this stuff out.  In person,
George is a really sweet guy who I enjoyed being with.  In person, he backs
down when he's wrong.

If you want to learn about the 1:30 rule from someone who actually
understands it, try http://www.werple.net.au/~kiewavly/bases.html.  Note
the graphs near the bottom.  Compare the formula that Bercovitz calls "the
most accurate method" (#1), with George's 1:30 rule (#4).

This thread is a waste of my time.
