The *level* of the list is based on 337 games played against humans in serious
tournaments between 1987 and 1991.

The relative ratings are based only on comp-comp games, played on the tournament
levels.

When we change hardware we use to play 5-6 programs on the old as well as on the
new hardware, in order to get information about how many rating points the
hardware in average gives. Hopefully we can do so next time also.
