I agree that the 2400 is useless.
We do not know rating and I think that we have no ssdf rating or WBEC rating for
the participants even in part of the cases(different hardware and different
versions and different books).

It was possible to add 3000 elo to all engines so nobody will connect that
performance with rating.

The point that I responded was the place of Diep in the table.
The place of Diep in peter's table is still correct or close to correct.

You say that not all the games were used and it is possible that more games can
change the place of diep in the table but it is clearly logical that diep will
have worse performance table than place in the official table.


Diep played the weakest participants and did not play hydra.
Some players with 4.5 played stronger opponents so their 4.5 points give them
better performance than diep.

I agree.

My point was about the ranking in the table and not about rating(I admit that
the ranking may be wrong because of not using all the games but I see nothing
illogical in place 11 for diep in performance table).
