I am trying to understand why my device sometimes tracks intensity minutes, and sometimes not. I leave the HR monitor on 24/7 so I get a good resting HR around ~56bpm most days. Yesterday I took a fairly vigorous hike and racked up 0 intensity minutes. I am having a heck of a time getting to the 150 goal because of issues like this. Meanwhile, hiking my dog this morning (had to sniff everything) racked up 10 minutes, and it wasn't even close to vigorous other than mashing my way through 12" of crunchy old snow trying to get to work on time.
I manually set my peak heart rate to 166bpm, which is supposedly my peak for my age at 48yo. I can't even get close to this while playing hockey, maybe 148bpm is the highest I have seen. I am not sure if by manually setting it lower than the default of 177bpm messed up the intensity minutes calculation for hikes? It is almost impossible for me to get into the anaerobic HR range, my ticker is willing but the body is weak.
I get plenty of credit for hockey, but 2hrs of it only usually registers ~35minutes of intensity. This was before I lowered my peak heart rate though, I expect it to go up next time.
This is the hike:

Please take a look at the HR zones, and the HR over time and I think it has to do with the duration at any one time of peak heart rate? Climbing a hill doesn't take long enough to register? These hills may not be the largest, but when almost running up them, I hoped for a little credit!
Thanks for any insight.
