Scoring

As the National Ranking Series are restricted to current full members of Triathlon England, Welsh Triathlon or triathlonScotland, the rankings are calculated using only members' results i.e. in a race with 500 competitors, 300 of which are Federation members the field size is 300 for the calculation of ranking points. The calculation is based on the competitor at the 40th percentile position in the field (i.e 39% of the field finish in front and 59% of the field finish behind) who is awarded 100 points.

Thus, in an event with 300 Federation members, the 40th percentile position would be 120. If their time is called T40 and their time is Tx their ranking points are calculated as: 100 x (T40 / Tx)

And, in a race with a T40 of 90 minutes points would be awarded as follows:
Competitor A - finishing time of 60 minutes - ranking points are 100 x 90/60 = 150
Competitor B - finishing time of 80 minutes - ranking points are 100 x 90/80 = 113
Competitor X - finishing time of 90 minutes (40th percentile) - ranking points are 100 x 90/90 = 100
Competitor C - finishing time of 120 minutes - ranking points are 100 x 90/120 = 75
