Intensity minutes cycling activity different from intensity minutes calculator in app

Fenix 7S and HRM Pro: After cycling activity of 98 minutes I accumulate 174 intensity minutes consisting of 16 min moderate and 79 min vigorous (this seems correct). But the intensity meter in the app and on the watch registers a total 301 intensity minutes. The graph shows a sudden addition some minutes after the activity. This is abnormal and did not happen prior. Any suggestions?

  • Getting similar recording on edge 1050 and HRM pro plus, rides recorded intensity minutes ok. Either when HRM or fenix 7 syncs to connect intensity minutes double ?

  • I’m getting similar strange results with my intensity minutes. I’m just doing light workouts on a stationary rower and treadmill, walking. Consistently for the past 7 days, the nearly whole workout it being counted as vigorous so doubling my total intense minutes. Looking at the individual workouts it just shows moderate minutes and 0 vigorous which is what I expect. Looking at Intensity Minutes l have most of the time as Vigorous. Posted on Reddit also without any suggestions. My HR and calories are as expected.
