The Elo system is calibrated so that that the expected value from playing a player 200 points stronger than you is 0.24. This is true independent of the strength of the players. If you are scoring 0.10 against players 200 points stronger than you (that would mean, for example, 1 draw and 4 losses over 5 games) but maintaining a stable rating, then you must be crushing players that are weaker than you and/or doing very well against players at your level.

(FWIW, I am 2000 USCF and an expected value of 0.24 vs a 2200 and 0.76 vs an 1800 feels quite reasonable to me.)

Elo assumes that performance across n^2 players fits the logistic curve model of n players. There is no reason to believe that assumption is remotely accurate and that Elo would ever stabilize. Players often avoid playing lower rated players, for this reason.

Is the current ELO accurate though? How many fide rated games were played over covid?

Elo is not an acronym.

Indeed. It stands for Extra-acronymic Language Object.
