The simple fact is that in a tournament the players are not prepared only
against one player.

There is another reason to assume Rebel would do better in a tournament

The reason is very simple:
the level in chess is not transitive.

GM can be better than an IM
IM can be better than a computer
and the computer can be better than the first GM.

The first GM knows that Rebel is better than him(her) so (s)he is not going to
play against Rebel in this situation.

(s)he may play in a tournament when rebel is only one of 10 players (s)he is
going to play.
