Thanks to you lately I have been testing with 400 games, and this should be a good small sample to predict the outcome of what would be 800 or 1000 games. What I have noticed so far is that if two engines are equal from 40 games on .... the score pretty much remains equal throughout no matter if you test them 40 games 400, or even 1000 games. What you have to take into consideration is that there are some openings or not calibrated openings that are one sided that benefit certain engines even if the rating difference is 200 rating like a game that I saw between Rubichess and Stockfish 3 JA and no matter if they play Blitz or longer T/C the result was the same. Therefore, when two engine like these two are equally strong only a bad opening can cause one side to win fast. The only reason why Micro-Max beat Glaurung was because of the bad opening and the same happened when Stockfish 3 JA Drew Vs Rubichess forum3/viewtopic.php?f=2&t=80224. For instance you can take this bad opening and use any two engines rated about 200 rating apart and the weaker engine can at least draw. If you want give it to Rubichess Vs latest version of Stockfish and you will see the result
