You couldn't run the games yourself since you didn't know Jounis configuration.
You can run a lot of different timecontrols of course, but the chances of
examining the same timecontrol as Jouni were next to nothing.

A very sensible move, since you are now independent of the results obtained by
Jouni.

This is not true and I think you know it.

The learning may or may not be important, but it's a factor in the equation. A
big factor IMO and one that could/should have been removed. If you claim that
your test proves anything, you're bound to receive criticism, however valid it
may be. I don't see why the lack of comments on Jounis result have anything to
do with this. Your test was much more extensive and advanced than Jounis,
therefore results and their interpretation was more important.

Hmm... I don't think anyone considers you to be a Crafty hater. There were small
variables and there were big variables. You didn't bother adressing any of them,
so...

You're to fond of conclusions without the aid of fact.

You wrote in the beginning of the post that the reproducing the Jouni test was
only an interest, which developed into a question of ponder. What is the
truth?If your objective was to disprove Jounis test, you have to continue
testing. Since you believe that your test was productive, I would like to know
_one_ single thing: What comparable data did your test produce? The reason I ask
is that I haven't seen any yet.

Why didn't you just state in your first post that the evaluations of Fritz and
Crafty had been checked? Instead you wrote that you replayed the games and
selected the 15-5. I think you're bending fact to accomodate your conclusion.

Please post them when you can. And the IP adresses as well of course.
