You wrote "He finished 0.91% of his victories" and "and was finished in 0.87% of losses"It's exactly how percentages work lol
In 47 fights Melvin had 5 fights that went to decision. That means in 89% of his total fights someone (either his opponent or Melvin himself) got slept or tapped.
The way I expressed it earlier simply took the percentage of the wins and the percentage of his losses as separate entities.
0.91% and 0.87% != 91% and 87%
lol
