No
We cannot say it.
The correct rating is not based on games against one player and 100 elo
difference is not so big that 3-3 is impossible.

I guess that they need to pay more money for it.
Programmers are not rich people and they cannot let themselves to pay a lot of
money for a match.

I suspect that >2700 performance against 2500 players is not more productive for
a commercial program than the same performance against 2700 players.

I do not.
I think that getting performance of 2700 against 2500 players is not easier than
getting the same performance against 2700 players and tiger's performance was
better than Deep Junior's performance.

If you use the same logic you are going to find that the rating of humans is
wrong.

There were tournaments of 9 games when I got performace of more than 100 elo
better than my rating and tournaments when my performance was more than 100 elo
worse than my rating.
