I agree with this, but I understand how people find it difficult to believe that there can exist such an outlier. It kinda goes against the gut feeling that at the top they all must have the same genetic aptitude. The reality is the more of an outlier something is, the bigger the distance to its nearest neighbor is.
I have often referred to some outlier where it is very difficult to suspect cheating. E.g., Fisher and Kasparov at chess and certainly Carlsen who is dominant across a vide variety of chess time controls and disciplines (Fisher Random). Another example are the best mathematicians in history such as Archimedes, Newton, Gauss, Euler... Even is someone thought that it is possible to cheat at chess and hence the dominance of the players above there in no way to cheat at math and yet we have people such as the ones above. It is ridiculous how much better they were than their contemporaries. And, I guess so is Pog. Except for Rog who is going to win it all this year
