Intensity minutes (IM) have not included any vigorous minutes in last 2 weeks. I use a FR 245 and Instinct Solar. I have user settings set to calculate IM based on time in heart rate zones, with moderate in zone 3 and vigorous in zone 4 (and presumably zone 5). On my most recent cycling workout, I recorded 28 minutes in zone 3, 36 minutes in zone 4, and 11 minutes in zone 5, however 0 vigorous minutes were recorded. This lack of recording any vigorous minutes has changed sometime around 2 weeks ago without any intervention on my part.
