What the fuck are you talking about?
First off, as was explained multiple times, accuracy is not a score, and is often actually a detriment for not being more aggressive/active
Secondly, you're using the TOTAL accuracy, which is not how you score a fight. As a matter of fact, the accuracy of round 3 was Jon at 55% and Dom at 57%, so even if you DO count accuracy, Dom wins AGAIN.
Thirdly, you're implying through some kind of unexplainable logic that Dom missing 19 of his strikes means the 26 he did land weren't impactful, but Jon only missing 15 strikes means his 19 landed strikes were more impactful and I can't even begin to explain how stupid that is.
