Hi Uri,

one thing I can tell you with 100% certainty is that all of these CM10th
settings are better than the default CM10th settings as the time control gets
longer.  I can provide proof of this if you require it.

When I joined CEGT, I was asked to run the 6+6 tournament I'm running involving
6 CM10th settings and 6 top engines.
As I was also restructuring my CM10th Showdown tournament at this point in time,
I offered to rerun it as a CEGT tournament.

Note also that only the one setting of any program is included in one of the
rating lists.

I feel it's a little bit like sour grapes to start questioning the worth of CEGT
now that Fruit 2.2 Uri isn't performing as well as hoped.

Regards, Graham.
