I made comparison between Carson's latest human list and SSDF to clear possible level difference. But it's very difficult, when there are not many exactly same software and hardware combinations. I removed multiprosessor results and made assumption, that difference between 200MMX and 450 Mhz is 79p (for comp-comp, sure not for human-comp). Here's some figures: Program average speed Against humans SSDF rating difference Rebel 431Mhz 2549/33 games 2594 (200MMX+79p) -45 Fritz6 500Mhz 2457/15 2721 (450) -264 Hiarcs6 272Mhz 2573/20 2518 (200MMX) +55 Shredder 500Mhz 2495/8 2676 (450) -181 CM5/6K 375Mhz 2521/14 2653 (200MMX+79p) -132 This means, that average difference (Against human - SSDF rating) is -85p. (Weighted difference for all 90 games). I think this confirms general feeling, that SSDF must drop level by 100 points. Counting these multiprosessor Junior/Fritz may still lower level. I this this kind of list is much more reasonable than current: 1 Fritz 6.0 128MB K6-2 450 MHz 2621 2 Junior 6.0 128MB K6-2 450 MHz 2589 3 Chess Tiger 12.0 DOS 128MB K6-2 450 2571 4 Fritz 5.32 128MB K6-2 450 MHz 2554 5 Nimzo 7.32 128MB K6-2 450 MHz 2553 6 Junior 5.0 128MB K6-2 450 MHz 2526 6 Hiarcs 7.32 128MB K6-2 450 MHz 2526 8 Crafty 17.07/CB 128MB K6-2 450 MHz 2524 9 Nimzo 99 128MB K6-2 450 MHz 2523 10 Hiarcs 7.32 64MB P200 MMX 2477 11 Fritz 5.32 64MB P200 MMX 2475 12 Chessmaster 6000 64MB P200 MMX 2474 13 Hiarcs 7.0 64MB P200 MMX 2460 13 Fritz 5.0 PB29% 67MB P200 MMX 2460 15 Nimzo 99 64MB P200 MMX 2449 16 Junior 5.0 64MB P200 MMX 2437 17 Nimzo 98 58MB P200 MMX 2425 18 Rebel 9.0 47MB P200 MMX 2420 19 Hiarcs 6.0 49MB P200 MMX 2418 20 Rebel 8.0 51MB P200 MMX 2410 Jouni
