If a 550 is beating another 550 then that 550 is not a 550 but higher. I mean just read the line again. I don't think you understand Fargo too well yet, it's the same thing that people were talking about when they thought the women should be ranked lower than the men. Someone is a 550 because they play even against other 550s. There is no 550 that will "smoke" another 550 because then that 550 would actually be a 600 or higher simply due to the fact they are beating other 550 ranked players. 550 is a 550 is a 550. If whoever you think is a 550 with "holes" in their game, then they would be a 500, or a 510. So either it's a 550 playing a 510, or it's a 550 playing a 580 or 600, or whatever, but it's not two 550s if one is always beating the other.
I mean it's pretty much the opposite of the point of the original post I did, and all the replies. You are trying to inject your own logic into a statistical rating. Saying someone is not this rank "just because" of something is like saying Napoleon would have ruled the world if he did not take that left into Russia in winter. He did, he's not. If someone is playing at a certain level, that is the level they are playing at, there are no 600 players that should be 650 due to a single thing, they are 600 players because they don't have the skill to play even with the 650 players, period. Why does not matter. They may just be nervous all the time and lose, or they hate blue and always miss the 2 ball, or mechanics are off, it does not matter. Once someone accumulates enough games against various opponents, they are what they are (barring cheating of course).
