Upload a GPX file with power data to generate a 3D power curve.
The surface shows how your best power decays across duration and repeated on/off efforts.

Power × Duration × Repeatability
A 3D power curve built from your ride data. The surface shows the best average
power achievable across duration and repeated on/off efforts of equal length.
How to read this:
Front edge = standard power curve (1 effort).
Depth = repeated efforts with equal rest.
e.g. 3×30s = best avg of 30s on, 30s off, 30s on, 30s off, 30s on — found by scanning all possible windows in the ride.
