Our ranking system requires a player to register a minimum amount of results in each time period in order to qualify for a ranked position. Each player will be required to play in at least 6 events to earn a rank.

I thought for a very long time of a way to give a fair result to a player and had many factors to consider, and I believe this ranking system is the most fair and accurate method possible. The Percentile Ranking works as follows:

When a player finishes in "X" place out of a total of "N" players in an event, he/she achieves a "Percentile" score of :

(1 - (X / (N + 1))) x 100

A player's ranking would be based on his/her average "percentile" score, averaged over however many tournaments he/she plays in a particular time frame once the minimum qualifying amount had been played. That is, there is no real advantage in playing more often. So on this basis, finishing 4th in a 10-player event would be worth approximately the same as finishing 6th in a 16-player tournament.

An example from the formula above:

Finishing 4th in a 10-player field = 63.64 "percentile".
Finishing 73rd in a 200-player field = 63.68 "percentile".
Finishing 10th in a 50-player field = 80.39 "percentile".
Finishing 98th in a 500-player field = 80.44 "percentile".

Overall ranking for a player achieving those four results would be:

(63.64 + 63.68 + 80.39 + 80.44) / 4 = 72.04 "percentile".

This means that on average, this player is beating around 72% of the field.

This will be called the "Percentile System" or something close.
