The advantage is that the system identifies unreliable ratings. The actual system is quite old, it does not take the Standard Deviation into consideration. Sandbaggers who looses to 1500 players and defeat 2400 players would have their rating flagged as unreliable by the new system. Australia considers that only very reliable and reliable ratings should be used on the Australia top players list.Originally Posted by Vladimir Drkulec
Any formula that gives both a value and a measure of the confidence of that value is preferable to a formula that only gives a value. Doing ratings the Elo way is becoming more and more obsolete as time pass. Instead of being subjective, the reliability of a rating becomes both objective and measurable. FICS has already moved away from Elo ratings and new endeavours, such a Couter-Strike GO computer gaming, have begun rating with the Glicko formula.
When enough member countries will have moved away from Elo, FIDE will likely follow.
