Some guy told me about it who has a law degree from U. Chicago and an MBA from the London school of economics. I have never done nor do I know how it works but it was a concept he told me about. Whether or not it is plausible is debatable and like the law "it all depends"
Also I mentioned the blue pencil and step down provision in a contract a while back but nobody did any research on it. Here is a PDF that is an interesting read.
