It's not as "grey" as you might think. Of course, the formula relies on many games being played to bring down the margin of error. Perhaps one of our engineer's will post up the formula again. Certainly, any program will have a "run" of luck (good or bad), in a tournament, sooner or later. >The answer is short.

If you bet on the 100 meter race, and your man loses by half a hair's breadth - be ready to pay up! Same with Olympics, NCAA, NASCAR, etc. If their measuring devices can detect who is the winner, that person is declared the winner, straightaway. No astrology or Eastern philosophy needed. The winner is the winner - unless it's a French ice skating judge, of course! :) David
