The background information of how BOR works is now on a separate page!
BOR is ranked by MR, which is the average score that players obtain from PR and SR.
The value of (PR - SR) shows the difference in the magnitude between PR and SR. If it is positive it means players score lower in SR than in PR on average, and vice versa. Since players' SR will consistently grow we expect the value of (PR-SR) will drop consistently. If it drops to some low level we need to readjust the penalty of SR.
The first ranking created on 18 Jan 2001 can be viewed here.
The BOR data file for the current week can be downloaded here (see forum for update announcement).

If you have some tips please tell me and I'll put them on the list -- and you will be credited!
Feel free to ask me for advise on what strategy to use for a better score. In addition I am also happy to give you some "hypothetical scores", like answering: "What would be my score if I had 50 more points in Bricks I?", "I am in a team of 2 with a score of 42000 in Bricks IV, what score is needed for an individual to have the same SR score as mine?" ...
It is quite clear that the average scores in SR will increase over time. This is due to the improvement on scores made by players; on the other hand the average scores in PR will remain stable (but individually players' scores might decline slowly -- let's see). As a result the constant "Decay Rate per 0.01%" in SR needs to be increased regularly (e.g., quarterly). The team penalty will remain unchanged.
Special thanks to the following friends from Bricks:
