The typical expectation is that as the length of a physical effort increases, the maximum average power for that effort decreases. There can be exceptions to this assumption in the Power Duration Curve.
This data deals only in your known and recorded running power data. It is possible for this type of data to occur during U-shaped intervals where a runner starts out at high power, sags in the middle, and then accelerates at the end. This is one instance, but other cases may be possible.
For this reason, Stryd® provides a modeled ability curve as well:
The contradiction can be corrected by targeting a higher power for the duration showing a lower value, and most times this is achievable.
