ERG all-rounders

  The above ranking uses the so-called P/AR metric. This metric (in Watts/year) 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 included.  See  here  for a more detailed explanation on this ranking metric,

  The P/AR ratio  Vianney Koelman  Dutch Eindhoven Rowing Association Beatrix    Cyclists are used to a power-to-weight (measured in Watts per kilogram) performance metric. The power-to-age-reserve ratio (abbreviated as P/AR and measured in Watts per year) provides us with a 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 data points. These straight lines effective...
