Whenever there is a controversial decision in professional boxing, fight fans that disagree with the scorecards check the punch stats.
Sometimes the losing fighter lands more punches than the winner.
If that’s the case, fans of the loser call the bout fixed. They refuse to believe that a fighter can land more punches and lose the decision. So the controversy is created by the fan’s refusal to accept the decision and not necessarily a problem in scoring.
The official rules of professional boxing score a fight on: Ring generalship, effective aggressiveness, and clean punching.
Notice, the rules don’t mention the highest total of landed punches.
Until recent changes, amateur boxing counted one point per-landed-punch, and after three rounds, whoever had the most points won.
Problem. The total punch count doesn’t distinguish between per round activity.
