It seems to me that Ruffian 1.0.5 is still clearly stronger. Ratings from a few
of the most
popular public rating lists (notice that in all lists, the error bars are much
smaller than the
above):
Rating + - Games Score Av.op Draws
UEL:
1 Ruffian 1.0.5 2654 18 23 879 66.2% 2537 27.2%
3 Aristarch 4.50 2602 26 27 507 59.8% 2533 27.6%
AEGT:
2 Ruffian 1.0.5 2760 46 54 152 63.8% 2662 25.0%
3 Aristarch 4.50 2749 47 52 152 62.2% 2663 25.7%
HvK Nunn list:
10 Ruffian 1.0.5 2754 19 24 762 66.0% 2639 29.9%
15 Aristarch 4.50 2692 18 25 882 67.1% 2568 24.0%
YABRL:
7 Ruffian 1.0.1 2649 16 22 1015 67.7% 2520 27.9%
10 Aristarch 4.50 2614 17 19 1117 60.8% 2538 26.6%
Looks rather convincing to me.

ProDeo and Ruffian, yes, but I am not at all sure that Aristarch is number
three. List
is probably stronger, perhaps also Thinker. It is also not impossible that the
new versions
of AnMon and Pharaon will be close to the top.
