The Diamonds monthly P/AR competition

  The Diamonds monthly P/AR competition  Vianney Koelman  Dutch Eindhoven Rowing Association Beatrix  and The Diamonds (Over Sixties Erging Group)   Cyclists are used to a power-to-weight performance metric measured in Watts per kilogram. The power-to-age-reserve ratio (abbreviated as P/AR and measured in Watts per year) provides us with a somewhat similar metric. The objective of this novel metric is to create a level playing field across sexes and ages for ergometer events such as  RowErg  and  BikeErg  competitions.  So what is 'age-reserve'? We are all aware that once we enter our thirties, the power our bodies are capable of generating will gradually drop. Every year we grow older, the odds are our power figures will be less than those from a year before. This also holds for world-class athletes. As an example, below figure shows the power delivered by male and female RowErg 2k world record holders against the athlete’s age.  Straight lines fit nicely through both sets of

  The above ranking uses the so-called P/AR score as performance metric. This P/AR score (in Watts per year of age reserve) is formed by the ratio of power (in Watts) over age reserve (in years). Here, age reserve is the maximum number of years ahead of you: 120 minus your age. For females a sex-correction multiplier (equal to 1.56) is applied to the Wattage.  See  here  for a more detailed explanation of this ranking metric. Also note that the only ranked results that contribute to the leaderboard are verified scores or race scores. Unverified results are  not  included. Your results are included only when you have uploaded all three distances as ranked (and verified) results. The 2021-22 season closed April 30th 2022, and that also closes this competition. You can no longer upload new scores.
