No intervals detected ... again

There have been reports about this before. But these rides are a little different from
the others I have seen in the forum for which interval detection had failed. So here you go …

Any thoughts?

Here are the power data for one of the laps.

Hi @david
Is there something wrong on these workouts? Interval detection shows on workouts prior to these.

I think something might be wrong with the power data for that activity. It is very choppy if you zoom in a bit. Doesn’t look normal.

I think that is breaking the interval detection.

Have a look at the course. It’s plenty of turns on a 2 km course. So it’s: accelerate, brake, turn, repeat. Intervals only, if you will.

The power curve would look even “crispier” with a different GPS device. My Fenix watch is smoothing the data somewhat. (I did the comparison once on the same course.)
