I have to agree with Paul, I think this patent was a waste, if you want to share something, publish it with one of the many licenses available for free. Surely this would have cost less than the patent process. Further, I Personally, think this is another "imaginary property" type patent, such as the one filed recently by an entertainment company where you interact with the game by throwing the display, or many of the other process patents check this link out

for some examples.
Further, If a competition wanted to use this equation, if they simply said that the opponents score was factored in, could fist force the other competition to divulge its equation? Or could you conceal it under the guise of a "trade secret"
Hrmm, I wonder if the method of posting a message on a forum has been patented yet...
