I have not said that I would prefer 11.2 over 11.5 so far.
All i can say is, that I told you that 11.2 was in my opinion far better than
11.4 ...

I have not come to a final conclusion. I would need special analysis to tell you
exactly how many elo-points the one version differs from the other.
In the moment i cannot do so because of the summer-tournament i have to play
plenty of games between all kind of programs.
Maybe later we have time...
In the mean time please win the french and spanish championship.
So that the people believe in my words.
I don't like to be wrong :-))

always and always people say this. I don't trust in statistics. Only in my own
feelings. Sorry. But - numbers are numbers are numbers on paper.
Nobody knows how these numbers have been realized.
Also i would never trust games version x against x+1 because the 2 engines are
too similar to get real data to trust in.

When i test a program it needs at least a month or 2.
Then i can tell you about it, but not earlier.
In this time i do all kind of things with the program.
Test-positions. Games vs. computers. Vs. humans. Old positions i know from
experience. When I am suspicious I construct positions. to see if my idea about
the reason it loses/wins is right.
