I know how the current SSDF rating system work, but newer version of programs
don't need to play against 10 others from the SSDF-List, it is sifficient just
to math the newer programs agains the six top from the previous rating list and
instead of just playing 40 games against each others, the number of games should
be increased to 80 to satisfy the materialistics; and to provide a more reliable
probability of the true strenght of these newcomers.
