Unless 2 people dance around the center logo for 5 minutes and never make contact, or punch each other the exact same number of times with the same exact same amount of force each time, then you could conceivably argue that a round should be scored 10-9 rather than 10-10. I understand that. However, since some people do score 10-10 rounds, and because they're allowed to, I just take that as a round that could have gone either way in their view. You have to work with what you've got. Telling people not to score 10-10 rounds when not even the rules say they can't, is probably fruitless.
