lways use the latest version of one day, if more than one version per day is released. And I use the version "for modern computers". (At the moment, the compiles for modern windows machines on abrok.eu are around 8% slower, so I dont use them anymore) Each Stockfish-version plays 1000 games against Komodo 10.4, Houdini 5, Shredder 13, Fizbo 1.9, Gull 3, Fire 4, and Critter 1.6a.

Below you find a diagram of the progress of Stockfish in my tests since the end of 2016. And below that diagram, the older diagrams. You can save the diagrams (as a JPG-picture (in originial size)) on your PC with mouseclick (right button) and then choose "save image"...The Elo-ratings of older Stockfish dev-versions in the Ordo-calculation can be a little different to the Elo-"dots" in the diagram, because the results/games of new Stockfish dev-versions - when getting part of the Ordo-calculation - can change the Elo-ratings of the opponent engines and that can change the Elo-ratings of older Stockfish dev-versions (in the Ordo-calculation / ratinglist, but not in the diagram, where all Elo-"dots" are the rating of one Stockfish dev-version at the moment, when the testrun of that Stockfish dev-version was finished).
