Irrespective of the primary means of evaluating the strength of the two relative positions in a single game of chess viz.

Average centipawn loss is one of the key benchmarks, though it does take a little extra analysis for it to make sense from a human perspective. This is more in line with how computers evaluate chess positions rather than our typical understanding of play: though we do have a direct correlation in the value of pieces and pawns, positional errors are tougher to quantify with this metric for the human mind. As chess players continue to improve, the average centipawn loss continues to drop at all levels of play. However, there are clear differences between various levels of competitors. For the best human players in the world—meaning Grandmasters and super-Grandmasters—an average centipawn loss between 20 and 10 is to be expected.

Doesn't it depend on the game? If you play games that end early, you can get a lower centipawn loss by virtue of simply not having mistakes in the endgame. Also, do you mean opponents "are" or are you talking about one opponent? I see a mix of wins and losses in your recent history. That tells me there should be some higher centipawn loss games by your opponents. Maybe you resign later than your opponents, so their same centipawn loss is averaged over more moves. For example, if you play a lot of weaker opponents, it is going to be easier to find the best move and capitalize on their mistakes, and so you will have a lower cpl. Your opponent might have trained himself to play the sort of moves the computer likes. That's quite possible. The onboard engine is only any good with fairly immediate tactics. If all my moves were the same as the engine's, I would assume I wasn't playing well. The engine's assessments can't be trusted. I can think of a few games where, if I'd played the engine's moves, I wouldn't have won because the engine line was drawn by force. Why choose median over mean?

As a starting point, I thought that it might be possible to approximate a player's rating by looking at their average centipawn loss. The average centipawn loss aCPL is the amount by which a chess engine's evaluation of the position changes after each of the player's moves. I thought that perhaps stronger players would have a lower aCPL, such that it would be possible to approximate a player's rating from their aCPL.

Although even a master will be making calculations around exchange and sacrificial situations as to whether there is a material advantage on the other side.
