Intensity Minutes and Timing don't match

The HR chart doesn't tell how many intensity minutes you should get. If you average resting HR changes the HR ranges used will change.

"Your Instinct® Crossover watch calculates intensity minutes by comparing your heart rate data to your average resting heart rate."

Earning Intensity Minutes

Hi e7andy,

Thanks for the feedback, but this is not correct. If you look at the time of the activity, it tracked 52min, nearly 36min of those moving. I'd bet that for more than 50min my HR was above my resting HR of 52bpm. You can check this by looking at the HR zone diagram if you want to be sure. All captured zones are above my resting HR. The watch (or online app which received the data from the watch) only tracked 17+7=24min in total. Something's definitely off here. And I never had these issues before, this is new.

Cheers.

Just being above the resting HR will not make you earn intensity minutes.

My general rule is that you get moderate intensity minutes for zone 3 and vigorous for zone 4. It isn't that simple here since it uses resting HR but it seems to be close enough. In some watches you can define the zones.

So, you had 17 minutes in zone 3 and got 17 moderate minutes and you had 9 minutes in zone 4 and got 7 vigorous minutes. 

To me that is close enough.

That makes kind of sense, i agree.

I have checked other activities and with a lot of good will it is possible to apply this logic to some of them too, whilst with others it does not work at all. Would be nice if we could know the exact methodology ...

Also, looking at the HR graph, it seems something was off with the readings, which might have caused some of the weird calculations. Do you get that too sometimes? Do you know how to improve it (other than tightening the strip which i do before each activity)? 

Thanks for your help, much appreciated.
