I think this example might be better suited since there is more game history:
152 Ruffian 2.1.0 2649 = Your Rating
Match Score: (Same Tournament)
Res Ruffian 0.5 - 2.5 Elite 68060 V11 (2296)
142 Deep Sjeng 1.6 2CPU 2666 = Your Rating
Match Score: (Same Tournament)
Mephisto Montreux (2279) 3.5 - 1.5 Res Deep Sjeng 1.8
Bear in mind that Ruffian 2.1 and Deep Sjeng 1.8 are running at 200Mhz with a bunch of other bells and whistles.
I dont even see a 100 ELO difference between these. These are NOT flukes or lucky games.

I think that something is wrong with these results.
one possibility is that the programmers of ruffian and deep sjeng simply did not care to optimize their programs for the slow hardware
that is used and I do not mean different search algorithm but speed optimizations with the same algorithm.
Maybe it is possible to make ruffian or Sjeng 10 times faster on old hardware not by changing the algorithm but only by optimization for slow hardware that is not important for commercial programmers.
Another possibility is that the opponents are not normal programs but dedicated computers that were build only for chess and in that case I suspect that the mhz is simply misleading because hardware that is designed for chess has a speed advantage relative to software that run on computers with the same mhz that were not designed for chess.
I know nothing about
Elite 68060 V11 or Montreux and I wonder if they are chess software or dedicated chess computers that are combination of software and hardware like hydra.

Perhaps you are right perhaps you are wrong, without asking the programmers directly I will trust that Ruud Martin gave me Fruit 2.1, Toga 2 1.2, Ruffian 2.1, Deep Sjeng 1.8 etc in my Resurrection.
But like every collector of dedicated chess computers I am also curious about what I have so I do spend time playing around with it. So since I also like engines I am also curious about where my dedicated computers fit in a ranking. Therefore I am playing some tests to bridge the gap between dedicated and engines.
Humor me for a moment and look at this logic and if I am wrong somewhere show me where so that I can correct it.
1) If I take say 22 games at a start rating of 2400 and run them through ELO
Stat I would get approximately +134/-136
2) Generally everyone talks about +50-+75 ELO per doubling of CPU speed, so for my test lets do +62.5 ELO
3) My Laptop Info is: HP AMD Turion 64 Mobile Technology ML-321.79 GHz, 1.00 GB RAM
4) I want to test against Chess Engines on my Laptop but I want the Hash 32 MB to be about the same and no tablebases and at 30sec/move setting.
5) You show Toga II 1.2 with an XXX CPU as 89 Toga II 1.2 2761, I say on my laptop Toga II 1.2 engine using my play setting is about ELO 2650 (Still matches your ELO within the ELO Stat tolerances)
6) Now I know that I have to deduct about 250 ELO points (268 at 62.5 per doubling) to get the approx level to Test Resurrection Toga II 1.2 at 200 Mhz.
7) So who do I test against? Easy lets look at Division III 3rd Division edition 14 WBEC Ridderkerk for the opponents.
So after 22 Games giving Toga II 1.2 a start rating of ELO 2400 here is the current ELO Stat stats:
Program Elo + - Games Score Av.Op. Draws
1 Resurrection Toga II 1.2 : 2375 134 136 22 43.2 % 2423 22.7 %
Individual statistics:
1 Resurrection Toga II 1.2 : 2375 22 (+ 7,= 5,- 10), 43.2 %
Anechka 0.08 : 4 (+ 3,= 0,- 1), 75.0 %
Alaric 704 : 4 (+ 1,= 0,- 3), 25.0 %
Snitch 1.6.2 : 4 (+ 1,= 2,- 1), 50.0 %
Phalanx22 : 4 (+ 1,= 1,- 2), 37.5 %
Delphil 1.6c : 4 (+ 0,= 2,- 2), 25.0 %
Bruja v1.9 : 2 (+ 1,= 0,- 1), 50.0 %
As you can see sofar the results match pretty closely to what I estimated before I started. Therefore I cannot find any reasons to dispute Ruud Martin on the software he has provided. I plan to complete this test someday with all the Resurrection engines when I have the time.
There is nothing here sofar that tells me the software in a Resurrection is different.
PS. Mephisto Montreaux and Fidelite Elite V11 are both dedicated board computers !!
