Perhaps I can save Roger a few keystrokes, Scott. :)

The following URL leads to a post by George Booth which details the 
reasoning behind the equation he and Roger developed which Scott mentions

This next URL jumps to a post in which Carlos Munoz shows the mathematical 
link between Roger and George's equation and the one I posted for Greger.
