Hydra is not available so it is not relevant.

Shredder8 is not relevant because we have only one shredder in the list of
programs(otherwise Stefan can release 100 of shredder's and you can say that
other programs are even not number 100 in the list).

Fritz8 and Junior9 have lower rating than Fruit based on the CEGT list
