Clean punching should be weighed with the most possible points. It is by far the most important aspect of judging. The truth is clean punching accounts for probably at least 90% of a score. It should at least. Consider that the cleaner puncher is taking the defensive portion because obviously he's getting hit less than his opponent. And because he is the cleaner puncher he's obviously the man holding ring generalship and is really controlling the action of the fight. The idea is to hit and not get hit. Only in cases that you cannot determine a clear winner based on clean punching should you go to the next 3 criteria and many have a different opinion of what ring generalship really is and how much it should factor into a score. Effective aggression as well can be misinterpreted as simply the man moving forward or the man throwing a lot of punches. There's no need to score missed or blocked punches. We should only be looking at what is actually landing. Splitting the 4 criteria into points could only cause further mayhem among judges as everybody will have a different opinion on their value. The one thing that cannot be denied is that clean and effective punching should win the round.
