The AGF Rankings have been replaced with our proprietary AGF Rating system. This system is still in BETA mode while we test our algorithms and tweak as needed.
Expect numbers to change as we continue to make adjustments.What is the difference between the old system, and the new system?
A lot. The old system used division placement as the only factor for determining who is the better athlete.
For example, if Bob competes in 10 divisions and wins Silver in all 10 divisions, he would have earned 30 points towards his overall ranking. Fred competed in 3 divisions, earning Gold in all 3. Fred's ranking would be 27 points. This would mean that Bob is ranked higher than Fred. Even if Fred beat Bob in all 3 of those divisions. This is inaccurate.
With the new rating system, we value both wins and losses. A win will raise your rating, and a loss will lower your rating. The amounts lost and gained is dependent on the rating of each competitor, their belt ranks, and who won the match.What does this Rating mean?
As of right now, the rating is simply a competitor's probability of winning a match. When compared to another opponent in the same division, the competitor with the higher rating has a higher probability of winning the match.
As we continue to tweak the algorithm, the rating will be used to determine seed positions in brackets to ensure that the two highest rated competitors are on opposite sides of the brackets.
The Rating does NOT determine who is the best athlete at this time. The Rating is simply a tool we will use to later refine the Rankings.
