Here are some updated lists besides what Eric added, I added Mephisto I, Mephisto II 6.14 Mhz and CXG Super Enterprise.



Mephsito II 6.14 Mhz at tournament level scored well with 1581 ELO. This means I will have to also do Mephisto II 3.5 Mhz to see what it can do. I suspect other ratings might be a mixture between the two speeds. Mephisto I scored 1330 ELO which is almost an exact match to what SSDF shows. SSDF only played Tournament level. CXG Super Enterprise also scored 1687 ELO. Something to note with CXG both Super Enterprise and Sphinx 40 take a long time to play their moves at TM Level. They take mostly double the time. It is almost like the take back of moves resets their average time left. I might have to as a comparison use a 3 minute timer and see how they score by forcing the move at 3 minutes. Unless someone has any other ideas.



Funnily enough Mephsito I outscored Mephisto II 6.14 Mhz at 30 seconds per move. Level setting A3 = @ 20 seconds per move for Mephisto II.



The above is the speed doubling comparison for the all the computers that have so far completed 3 minutes and 30 seconds per move.

I also added the USCF classification as another interesting comparison and also the Renaissance period humans that played those games.

I just completed Mephisto II with the original speed of 3.5 Mhz at Tournament Level.

There is not too much difference between 3.5 Mhz and 6.14 Mhz. The difference being 28 ELO points.

I should have added that it makes quite a difference in the moves played as you can see in the scores of the different games. But it does not make that much difference in the final ratings.

Sorry I made a mistake in Game 1.

Here it is the information again:

There is actually only a 22 ELO difference.

Here is Mephisto III added at Tournament Level:

I think the final rating is quite consistent.

I just completed Mephisto II ESB.

Testing Mephisto II ESB was interesting and exciting. Up until the very last move in Game 10 it seemed that ESB would score ahead of Mephisto III but then blundered in the last move. Even though Schachcomputer.Info shows a difference of 37 ELO in favor of Mephisto III, there really is not much to choose between them. If you study the games list at Info, you will see that Mephisto III played 108 more games. Mephisto III lost to ESB by 13 - 10. But performed better against others i.e. losing to Superstar 28K by 10 - 8 compared to ESB drawing 5-5. Or as in Scisys Mk 5 ESB wins 15 - 11 whereas Mephsito III wins 12 -3. It is these kinds of differences that give Mephisto III the 37 ELO advantage.

So overall I don't think there is that much to choose between them at Tournament Level.

Playstyle wise as you can see from the above, Mephisto II, ESB and Mephisto III play different moves, so it is worthwhile having all three of these modules. The one game where Mephisto II and III scored the same, Game 8, the moves were different, so the score was coincidental.
