You still have to learn a lot about statistics and margin of errors...
Short story: there is too much randomness in a tournament like this one. You'd
better trust the SSDF list, where each program has played many many games before
it gets a rating.
If you don't believe it, run a "virtual" tournament where you decide the outcome
of the games by flipping a coin. All participants under these conditions should
be perfectly equal, but you will see one performing extremely well and the other
one performing extremely badly. How comes? Statistics...
