There’s been lots of issues with the way Wahoo records power.

I had a similar issue - Yet another baffling data discrepancy (Bolt / TrainingPeaks)
And this - Average power higher than NP - why?
The issues all vary slightly but most seem to centre around the problem that the Wahoo has a tendency to record “-” instead of “0” when the power meter isn’t being used, which skews the numbers when entered into training programs.
Can you link to your ride on TR?
