Wiki used an old SSDF formula which removed 100 ELO at a time when chess engines became popular. It was a way to make it fit with ELO's with the top engine programs of that time.Volodymyr wrote:Thanks Nick.
Very big difference Wiki ELO:1940,Manufacturer ELO 2294 USCF.
Why is that?
At Schachcomputer.Info the rating is 2010 ELO playing games at 30 seconds per move.

Karpov is the same computer as Novag Emerald Classic Plus. You can see a rating comparison here on line number 101:

Novag marketed the Emerald Classic Plus at ELO 2294 which was a little too optimistic. Novag, Excalibur, Fidelity and Saitek tended to base their ratings on USCF as it made them appear stronger.

Here at Mike's site in England you can also see Selective Search from Aug/Sept 1998.

Here it shows on page 32 line 179 Emerald Classic Plus against computers at ELO 2033 and against humans as ELO 2136. If you consider that very probably in the UK the conversion was more of an approximation for FIDE rating. Therefore USCF human rating would be approximately 2199 if you use the rating conversion chart at my website. So the optimistic rating from Novag was maybe 98 ELO too high at ELO 2294.
Selective Search is interesting as its reports were written at a time when humans still played against chess computers and the Selective Search list shows a nice comparison between the old pc/dos programs and board chess computers. It also shows a lot of board chess computers that are not shown separately elsewhere.
Starting to appreciate the efforts made by the people from Selective Search more and more the deeper I look into them.
