Even collecting the tags is too much to ask for with a lot of people!
On topic, I think there's probably enough people who are rated roughly as skilled as you are and with enough variables in the game, I don't find it hard to believe that people can regularly have games where they do well or they do badly.
Either way, even if it was dramatically swinging one way and the other, game to game, I'm ok with having some games where I'm top of the scoreboard and sometimes the bottom.
Better that than steamrolling a bunch of noobs, which despite protestations (edit: not directed anyone here), is what at least some players want, imo.
