For all those that do not understand the ELO ranking system in game like Rainbow Six, this is from the CTSF;

For ranking our players we are using an ELO ranking system developed by Dr. Arpad Elo. It's widely known for its use in defining the world chess rankings and if you are familiar with this system, we are using it with some minor variations. The chess ranking system has been a tried and tested ranking system for many years.

Unlike the USTSA points system which follows the concept of, "the more you play the more points you get". You must continually beat players "equal to your points" or "greater than your points" to continually gain points. If you're beating those players, then you should be gaining points. (NOTE: since the point system has been in use a relatively short time and because players were put into their rank at a set starting point [ex. Pro 2400 points]. It may seem that some players are continually gaining points, this will only continue until the players have spread/moved to their proper level. Once a player has reached his proper/actual level they will fluctuate slightly at that range until their skill changes.)

Every time you play a match, points will be awarded to the winning team and points will be subtracted from the losing team.

How many points will be determined by two things:

1. The ranking points of your opponent compared to your ranking points. If a 1000 point player beats 2400 point player at the COFC, the 1000 player gets close to max points (50), and the 2400 player loses close to max 50 points. If that 2400 player would of beat the 1000 point player, the 2400 point player gains almost no points, and the 1000 player loses almost no points. If a 1800 point player beat another 1800 point player, the winner would gain 1/2 max points, and the loser, loses 1/2 max points.

2. The maximum points allotted for that event. Regional Events (local draws, etc) are worth a maximum of 30 points per match. Larger Multi-regional events (WCFC, COFC), are worth a maximum of 50 points per match. The example in #1 above used the COFC and therefore the maximum points were 50.

In Doubles events the average points of the players on that team are used to determine ranking points.

Points are re-calculated match to match, so a player could start an event with 1800 points, earn 25 points his first match and begin his second match with 1825 points.

Some other points.
. Every player has a separate point value for doubles and singles on each official style of play - Tornado, Garlando (Fastball, Passage), and Bonzini.
. The points you earn on one table do not effect points earned on other tables.
. The points you earn in doubles do not effect your points in singles.
. The ranking system is not effected by how much money a person wins
. The ranking system is not effected by how much money was awarded at the tournament.
. The ranking system is not adversely effected by how often a player plays.

Currently handicapped events are treated as if both teams are of near equal ranking points. So you win, you gain 1/2 max points, a loss, you lose 1/2 max points. (just like a 1800 point player played another 1800 point player). For this to work correctly, the handicapping system must ensure that both teams have an equal chance at winning the match - this is currently under review.

Every player that has played in an event that is entered into our system earns ranking points. Only CTSF members have their ranking information and match histories shown on our website. Once a player becomes a member all their previous match information is then made available on the website.

If you would like a more detailed explanation of the CTSF ranking system, see http://www.canadafoo.../exp_ranks.html, and if you have any further questions about the ranking system, then please forward them to the CTSF rankings committee [email protected]

Thank you for your continued support,

The CTSF executive.

Do What?

Does this system apply to "Capture the Bonsai" matches too then

A few words about this clever man:

Arpad E. Elo, born 1903 in Hungary, emigrated to the United States at age 10. From 1935 to 1965, he was professor of physics and astronomy at Marquette University.

From 1935 to 1937, Elo was administrator of the American Chess Federation which merged in 1939 with the National Chess Federation to become the USCF. He was nine times champion or co-champion of Wisconsin.

Practically a Rocket Scientist!
