This section gives headline information about the player including their level, age group, which clubs they play for and any membership numbers they have. This information is received with the results but can be updated and completed by player members and admins.

Level confidence is the confidence the system has in the player's level. It goes up with more matches played and down with unexpected results. A player's level will change more quickly if their level confidence is low so it gets to the right level more quickly.

Possible duplicates

With many players playing in different leagues, tournaments, clubs etc., their results can come in from a number of different systems resulting in multiple profiles. This table shows players with the same name who are about the same level and who are therefore possibly the same player.

If you know this player and can confirm that one or more of the suggested duplicates in the table are them then please let us know by selecting YES and clicking SEND. We review these requests every day and merge those that look likely. Sometimes the players' history shows them to have been at different clubs on the same day so we may query those.

Alternatively, if you know they are different players then please let us know that too. The suggested duplicate will then be removed.

By helping us in this way, it ensures that all our players' results are combined into single profiles which is better for everyone and provides more calibration data for the system. You are playing your part in the accuracy of the system. Thank you!
