That's right.
But is had been said that ELO's of old programs one old machines are more
reliable because with these programes have been played more games.
This is an statistical argument.
After the Cadaques-Tournament you could read statistics of the tournament with
confindence intervalls etc.
My question: how can you calculate confindence intervalls without any
statistical conditions to hold?
