| What
is an ELO Rating?
The ELO rating system typically starts
players off at 1500 (average rating). As
players complete matches, their rating gradually moves towards their
ultimate playing strength. Sometimes, if the skill level
of the group can be estimated, the starting point may differ.
ELO is based on math and can be used to
give a good
estimate of the probability of a certain level player beating
another.

What is a good ELO Rating?
- In Chess, the World Champion might achieve
a standardized ELO rating of 2700 and more. In Backgammon, due to
the luck involved, the World Champ would achieve a standardized ELO rating
of about 2000.
-
- World Class BG player = 1900
- Advanced BG player = 1800
- Intermediate BG player = 1650
How do I rate vs. other BG
players/clubs?
At zRoundtable.com, we compute and compare ratings across various Clubs
and Leagues. We have come up with a standardized list which we call
a Zuperlist. Soon, Ace Point Club players will appear on this list.
Why do the ratings seem low?
The ratings shown here are based on monthly
tournaments since 1998; however, this still represents a relatively small
amount of games and "experience." Players are still
gradually moving to their "true" rating.
As players complete more matches and
tournaments, their ratings will tend to move towards their
"true" rating.
What is a rampup?
In backgammon, it typically takes
"experience" (you earn 9 points of experience in a single 9-point
tournament match) of more than 1000 (closer to 1500) before a player's
"true or steady-state" rating is achieved. This period of
"gradual change" is called the "rampup."
Since our data is "sparse," we
computed the actual playing strength of players (removing the
"experience factor" -- or rampup effect).
