Arpad Emrick Elo

ArpadElo The ELO system for rating chessplayers was named after its originator, Arpad Elo. Born in 1903, Elo emigrated to the USA when he was 10. Educated at Chicago University, he later became professor of physics at Marquette University, Milwaukee. He learned to play chess in his teens and played in a number of tournaments. He was champion or co-champion of Wisconsin 9 times between 1935 and 1961. He was active in the USCF (United States Chess Federation) from its founding in 1939. He spent 20 years developing and validating his chess rating system, which was adopted by FIDE in 1970 for international use.
His book 'The Rating of Chessplayers, Past and Present' was published in 1978 and is the definitive reference on the ELO rating system. Most chess organisations that perform ratings for players use the ELO system, or a variation of it.

Reliability Calculation

The server calculates a reliability factor for each player according to their actions in the past few weeks.
This value is influenced by many different things, for example if their settings are correct, if they had a timeout in a game, or if they have unannounced vacations, etc.
The value is always between 0 and 10.

New players start at 3.5.
After they set up their basic settings such as the country code, gender, real name, birth year, this value goes up to 5.
If they successfully start few games and also finish them in order, without timeouts, silent vacation, the value raises around 6.
As they finish more games, and as the time goes without any problem with them, the value still raises.
Players with many months of membership and with a lot of games and without any problems can go over 9.

This may help players to find the right opponents, and may give them an approximate view about their future opponents, without personally knowing them.
Protecting serious club members, players with too low reliability (less than 5) can't enter for new tournaments.
