First of all, test between the different CM personalities are quite worthless,
they produce results which does not represent their real playing strenght. In
contrast to all other testers I match the engines against at least 50 other
engines, which gives the most accurate results. With this method the results are
extremely reproducible. I made a test with Nemjet 3.05:
The first 100 games: Elo 2524.
The second 100 games: Elo 2524.
The third 100 games: Elo 2523.

Other engines behaved the same, therefore my method works very well.
