[net.sport.football] quarterback rating

Does anybody know the formula for determining a quarterback's
rating?  I saw an article in the Chicago Sun-Times today that
said Walter Payton has the highest rating possible - 158.3.
But it never said exactly how this was computed.  
Payton accomplished this by throwing two passes Sunday against
the Saints, both for TD's.  So his completion rate is perfect,
his TD rate is perfect, his interception rate is perfect (0) and 
his average gain per pass is "off the chart" (38.5)!  These are 
the 4 things that are used to determine the rating, but I need
to know the algorithm.
