UHO Top 10 Ratinglist with Stockfish Dev progression

The 10 strongest engines of my SPCC Ratinglist and the latest StockfishDev version are playing 1000 games vs. each opponent: 10000 games per engine are played. A RoundRobin Tournament with 55000 games overall !
Results evaluated by ORDO, reference engine is the latest official Stockfish (Stockfish 16 right now), its Elo is set to 0. Why? Because using my UHO openings spread Elo-results wider than balanced openings, so it makes no sense to set the reference-Elo to any "realistic" value of 3800 or so... And mention, that all Computer Elo (Celo) in the various ratinglists are fictional in these days of superstrong engines, because the Celos can not be compared with human Elos anymore and since a long time.

Latest testrun: 2023/09/17: Stockfish 230911 (+3 Elo to Stockfish 230824)
Reference point (opponent) is the latest official SF-release (Stockfish 16 right now).

Hardware: AMD Ryzen 3900 12-core (24 threads) notebook with 32GB RAM. 20 games are played simultaneously

Speed: Singlethread, TurboBoost-mode switched off, chess starting position: Stockfish 15: 750000 n/s

Hash: 256MB per engine

GUI: Cutechess-cli (GUI ends game, when a 5-piece endgame is on the board)

Tablebases: None for engines, 5 Syzygy for cutechess-cli

Openings: My UHO_2022_6mvs_+120_+129 openings are used (first 500 lines) (part of my UHO 2022 download).

Ponder, Large Memory Pages & learning: Off

Thinking time: 3min+1sec per game/engine (average game-duration: 8 min 7sec (little bit longer than the games of the SPCC-Ratinglist take (7min 45sec), because using UHO-openings lowers the number of early 3fold-draws a lot))

The version-numbers of the Stockfish engines are the date of the latest patch, which was included in the Stockfish sourcecode, not the release-date of the engine-file, written backwards (year,month,day) (example: 200807 = August, 7, 2020). The used SF compile is the AVX2-compile, which is the fastest on my AMD Ryzen CPU. SF binaries are taken from abrok.eu (except the official SF-release versions, which are taken form the official Stockfish website).

ORDO calculation fixed to reference-engine (Elo = 0)

Below the UHO Top10 gamebase recalculated with my Gamepairs Rescorer Batch-Tool. Realizing Vondele's (Stockfish maintainer) idea: "Thinking uniquely in game pairs makes sense with the biased openings used these days. While pentanomial makes sense it is a bit complicated so we could simplify and score game pairs only (not games) as W-L-D (a traditional score of 2-0, or 1.5-0.5 is just a W)."
