Different Regions within the EPA play different numbers of matches, hence these National Rankings are based on an adjusted figure. The adjusted figure is calculated by taking the number of points a player has gained and dividing it by the number of matches that the player could have played in up to that point in time.
Further to this, in the Senior section each Region plays a different number of frames within a match. The adjusted figure is further adjusted to reflect this. All figures are based on 4 frames per match. If a Region plays 3 frames per match the figure will be adjusted up by multiplying by 4 and dividing by 3. If a Region plays 5 frames per match the figure will be adjusted down, by multiplying by 4 and dividing by 5.
