We call this alternative the duncanSCORE.
Both the duncanSCORE and Age Grading provide an evaluation of an individual’s performance:
– Age Grading against the greatest performance of all time (“smoothed” to a best-fit curve) for your Age Group/Event
– the duncanSCORE against the best annual performances of hundreds/thousands in your Age Group/Event
They are 2 different philosophies.
