First of all you are comparing a final match score against part of the match
score.

I am telling you why Shredder 9 may have not a very good start.

Shredder 7.04 was lucky to have found a weakness in Junior 9.

Shredder 9 may will too or not. I did not tested against it so I do not know.
I only know that will win.

You are wrong in making conclusions in one match only...

How do you explain than Shredder 7.04 is loosing against Shredder 9?

Shredder 9 is the strongest Shredder and is about 30 points stronger than
Shredder 8 as people found out here too.
I say about because I am not interested in finding out exactly. I am already
working on Shredder 10...

Shredder 7.04 is weaker than Shredder 8, running in the same GUI.
