PSA ranking points are earned based on the outcome of a tournament. It doesn’t matter who you beat or who you lose to. Players receive ranking points depending on how far they advance.
A player accumulates points in 12 months period, and calculate an average point.
Example: 1) A player who has competed in 12 tournaments has to select their best 10 results. 2) Accumulate the points from the 10 tournaments. 3) Divide by 10 (the divisor is 10 for 12 tournaments).
