This confirms that only Houdini is better than Rybka 4.1 - not much progress in 2 years

Hello Graham, do you have a pgn file with all the games you played (since 2 years or more) with 8 CPUs, please ?

Also Critter results are poor, compared to both CCRL and CEGT lists it seems that it doesn't utilize many cores too well or maybe it's just bad luck due to insufficient amounts of games. Whatever the reason is, Critter should be strong at least like Stockfish or Rybka. What is your opinion guys ?

True, Critter has a LOS of some 10% against Stockfish here, but it's higher on rating lists. RobboLito also performs badly, the level of Hiarcs and Junior.

The longer the time control the better Stockfish ranks.
on CEGT 40/120 Stockfish 2.2.2 is just 13 ELO points behind Critter 1.6 , while on CEGT 40/20pb=on 44 ELO points

Probably a combination of both things that you mentioned, but more so the fact that it's a one off tournament with a limited number of games.

Not so few games, you should be proud of your 8-core tournament.
