Maybe you could just mix the results of your tests to get closer to the truth.
I run automatic tests against a given program here. When I launch a test, I
launch it on 4 computers simultaneously. Each computer runs a complete match
(both opponents are on the same computer). Here is a result I had recently (Oct
13, 1999):
Computer A: 59.4% (32 games)
Computer B: 48.4% (32 games)
Computer C: 65.0% (20 games)
Computer D: 50.0% (16 games)
Overall result: 55.5%
If you look only at the result of Computer B and Computer C, you can say: "OK,
there is a problem, let's find WHY".
But remember that on B and on C you have exactly the same opponents with the
same settings. Actually there is absolutely NO problem!!!
Now mix together the results of B and C: you get 54.8% (don't forget the
weights: I do (48.4*32+65*20)/(32+20)), which is more reasonnable and quite
close to the final result.
So even this 65% result I got with 20 games is rather far from what I get with
100 games (in the end I get 10% less). And the 4.5-2.5 result Didzis has
currently is close to 65%, isn't it?
