I guess that it does not gives more than 150-200 elo improvement because of
diminishing return that means that being twice faster give only 40-50 elo
improvement at long time control and not 70 elo.

It seems that public fruit is about 150-200 elo better than public Crafty.
I expect both WCCC fruit and WCCC Crafty to be better than the public version so
it seems to me that fruit and Crafty have equal chances.

Maybe Crafty has better chances because you could learn from Fruit's evaluation
so you improved Crafty more than Fabien improved Fruit but only you can tell if
looking at the source of fruit helped you to improve Crafty.

I also do not believe the +100 elo stuff for fruit in this version but the stuff
is only about fruit so I do not see how you get your conclusion about other
programs.

The +100 elo stuff was correct for Fruit in the past and it is a fact that fruit
improved faster than other programs

Fruit2.0 was already above Crafty level on one cpu and Fruit2.1 is slightly more
than 100 elo better than fruit2.0 based on the CEGT rating list.
