I think that 2600 USCF is eqvivalent to 2500 Fide and I know that the
performance of Junior based on tournament games against human is almost 2500

Junior4.9 drew against 3 GM's in tournament time control in Dov poret Memorial
Junior5 lost 1.5:0.5 in the last tournament against GM yudasin at turnament time
control.

If you add the improvemant in hardware and in the program then I believe that
Deep Junior should have more than 2500 fide rating.

If this is the case can you explain me How Junior drew against 3 GM's and How
Rebel drew a tournament game against Anand.

I agree that computer stiill play very weak in a lot of situation but it is not
so simple to get these positions in games.
