their scores with each other or consulting with one another. At the end of each round, judges must hand in their scores to the referee who then hands them to the clerk who records and totals the final scores. Judges are to award 10 points (less any point deductions) to the victor of the round and a lesser score (less any point deductions) to the loser. The losing contestant's score can vary depending on different factors. The "10-point must" system is the most widely used scoring system since the mid-20th century. It is so named because a judge "must" award 10 points to at least one fighter each round (before deductions for fouls). Most rounds are scored 10–9, with 10 points for the fighter who won the round, and 9 points for the fighter the judge believes lost the round. If a round is judged to be even, it is scored 10–10. For each knockdown in a round, the judge deducts an additional point from the fighter knocked down, resulting in a 10–8 score if there is one knockdown or a 10–7 score if there are two knockdowns. If the referee instructs the judges to deduct a point for a foul, this deduction is applied after the preliminary computation. So, if a fighter wins a round, but is penalised for a foul, the score changes from 10–9 to 9–9. If that same fighter scored a knockdown in the round, the score would change from 10–8 in his favour to 9–8. While uncommon, if a fighter completely dominates a round but does not score a knockdown, a judge can still score that round 10–8. Judges do not have the ability to disregard an official knockdown. If the referee declares a fighter going down to be a knockdown, the judges must score it as such. If a fight is stopped due to an injury that the referee has ruled to be the result of an unintentional foul, the fight goes to the scorecards only if a specified number of rounds (usually three, sometimes four) have been completed. Whoever is ahead on the scorecards wins by a technical decision. If the required number of rounds has not been completed, the fight is declared a technical draw or a no contest. If a fight is stopped due to a cut resulting from a legal punch, the other participant is awarded a technical knockout win.
