But in my opinion, most of the players who "evaluated" Andrey's skill actually play worse than him, and I'm not even excluding those who play significantly worse.

I don't idealize my own level of play. In online games, I consider myself a below-average player. But in offline games, I'm slightly above average. And it's precisely the offline experience that allows me to assess a map and the level of play. Moreover, I theoretically know how to play. Therefore, judging by the save files of that game, I saw that his level of play is not much better than mine. And it certainly doesn't reach the level of top players like Alex.
