"The CompuBox stats in no way, shape or form, determine a winner of a fight. The stats are used to enhance a telecast, show the estimated barometer of activity by both fighters and paint a picture of the activity on a round-by-round basis. Even though our database of over 5,000 fights (and counting) shows that a fighter that throws and lands more punches will win 90% of the time, the 10 point judging system clearly is the only way to determine winners in a fight."
