I never said that 2480 was good or bad. Only that so far is not a GM rating.
After these 10 games, and saying that 10 games are not enough to know, I
speculated that... etc.

In fact, I am not even sure that this 2480 has the same meaning as it would have
for a human player. People's strength is transitive, while in the case of
programs it is not. An example: during the Kasparov-Short championship, Short's
representative at the games broadcasted by the BBC used to explain the result as
being predictable given the difference in Elo. This can not be done with chess
programs, because of the intransitive quality I mentioned. So I don't really
know if the system of Arpad Elo applies to programs in the same way it applies
to human players. Again: what I posted was and is speculative, of course, but
not of the kind "good or bad".
