I agree, missing doesn't matter, it's about the strikes that hit. The real problem is that there isn't really a universally applied standard of how fights are being scored. We have fights in which they seem to look more at the amount of strikes landed, and at other fights they seem to look more at the impact of the strikes. Judges are really inconsistent.
I feel that a knockdown secures the round unless you were really dominating the round or the knockdown was more of a pushover. But 3rd round was definitely a hard knee, which was the most significant strike of the round. Fifth round was also clearly Anderson's. So I guess we disagree about the fourth, but must admit I'll have to rewatch that one. Don't remember it too clearly, just remember feeling like it was even going into the fifth.
