This is the first time I have experienced the Glicko system and I think it is a better system. It takes into account your opponent's strength to determine yours. Therefore if you play people way below your rating you do not get any points for winning. Whereas in the Elo system you do. I actually like this system better.
I seem to have got it wrong this website does not use the ELO system for rating the strength of a player but the Glicko. See link below
