user23767: I want to create something that will select an appropriate Stockfish difficulty setting automatically given the player's rating. The straight Stockfish v11 that I've downloaded has 20 difficulty settings, and various other settings for controlling thinking time. Is there a resource that has approximate ratings for the levels? If that doesn't exist, what method would be recommended for finding the approximate ratings of chess engines when I'm starting from scratch?
EDIT: Sopel gave a link some time ago, that answers the problem, although they did it in comment form so I can't mark it as the correct answer

user19332: They have a development pipeline doing testing based on one of the early versions.
I saw a graph of such test in some heavy loading page from Next Chess Move website:

Stockfish Development Builds

The development page gathering the test linked from the Fishtest wiki:

Stockfish Testing Queue

And for completion:

Fishtest GitHub Repository Wiki


user28052: There was some discussion on improving Stockfish levels to play more humanlike https://github.com/official-stockfish/Stockfish/issues/3635
dav1312 provides this ELO rating list, but it's not listed how it was derived:
0    1347
1    1490
2    1597
3    1694
4    1785
5    1871
6    1954
7    2035
8    2113
9    2189
10    2264
11    2337
12    2409
13    2480
14    2550
15    2619
16    2686
17    2754
18    2820
19    2886

I think lichess could very well keep track of rating based on all the people that play it like for other bots: https://lichess.org/player/bots. I don't think they do, though.

user25998: I am rated 1410 USCF.  I played all 8 Stockfish levels this past weekend, once with each color.  My record was 11-5.
I was 2-0 vs Stockfish 1-5, 1-1 vs Stockfish 6, and 0-2 vs Stockfish 7 and 8.
