At TCEC there is even a permanent running gag about how often somebody requests for a match between Carlsen and the computer. In my graphic above you can clearly see when the strongest commercial engine has definitely surpassed the level of the strongest human. In 2006 it was Rybka making any further matches between humans and engines futile and the gap only increased since then.
Testing of the best engines only makes sense today between each other. Last year I wrote in part 1 that I liked executing those tests but they were too time-consuming so something I wouldn't repeat often anymore. Naturally the corona-crisis suddenly erased my calendar and allowed me to pick up again this hobby. In the last year I organized a dozen of matches each of them consisting of 100 rapidgames (15min + 10sec) using different computers between each time newer and stronger engines.
It is hard to deduct from above table how much the progress of the strongest commercial engine was in the last year. Therefore I also did a comparison between Leela v22 (end of last year) and Leela v26 (now) with Komodo 11 on my new laptop. The result was amazing. Last year I was already impressed by the score of 62,5 - 37,5 in favor of Leela but this is small beer compared with the new score of 75 - 25 of the more recent Leela-version. That is about 100 TPR extra. In other words it is time to update Leela if you are still working with a version of last year (the best test-results on my computers were achieved by v0.26.1 with network J92-210).
