Hello @david . A cool feature would be to add the option to generate the power-duration curve after a given amount of kJ/kg, for example, 20 kJ/kg.
I use this to track durability in my athletes, but with significant weight variations over the years, the current curve (based on absolute kJ) becomes misleading. Having a kJ/kg option would allow for more accurate comparisons and better long-term tracking.
Unfortunately it’s not easy to do that. The curves are pre-computed for performance reasons and stored with the kJ for each curve. When you change the kJ break points for an athlete all the curves are re-computed. Would be nice to have it per/kg thought so I will see if I can think of something.
The fatigue curves are available for each activity:
