Ninety-ninety Law - Tom Cargill

"The first 90% of the code accounts for the first 90% of the development time. The remaining 10% of the code accounts for the other 90% of the development time."

A good list of laws found here (old but good read):

    Is it intentional that the development time adds up to 180%?
