The SSDF rating I find for the Mach III suggests the Mach III is rated 1993: Rank Program CPU CPU Speed Rating Var #Games win% Oppo rating 124 Fidelity Mach III 68000 16 MHz 1993 14 2410 52% 1980 what is your basis for "[BlackElo "2265"]" for "[Black "Fidelity EAG"]" below? Is this the USCF CRA rating for the Mach III? Or is your machine something different from that tested by the SSDF? Note that the SSDF rating has a very low uncertainty (14 Elo) because of the large number of games played (2410 of them). Other data has suggested that ChessGenius 1.2 on your machine ought to have a rating of perhaps 2000 - 2060 SSDF. Assuming that your Fidelity EAG/Mach III machine is the one above, then your match results would indicate a mean performance rating of 1993 - (16/10)*25 = 1953, with a 95% confidence bound of 14 pts (for Fidelity uncertainty) + 60 points (SSDF uncertainty at 100 games)* sqrt(10) [variance is higher for fewer games, goes at square root of number of games), for a total uncertainty number of 204 points, indicating that Chess Genius rating would be in the range 1749-2157 with 95% confidence. Note that this uncertainty (204 points) in a rating based on a match of only 10 games is very high, which is why the SSDF ratings won't even print any ratings for a program that they don't have at least 100 games. However, better to have some data than no data. Were you planning to continue the match? If you played another 30 games, then the uncertainty drops to 109 points?
