Daily summary active minutes in Activity Time Series API

[new_developer]

I am looking at the daily summary of 'minutesSedentary', 'minutesLightlyActive', 'minutesFairlyActive', and 'minutesVeryActive' obtained from the "Get Activity Time Series by Date Range" API. I realize that some posts were talking about the definition of these four categories (seems based on MET and might be inconclusive), and I am skipping the definition here.

From my 5+ months data, the sums of the four values are usually 1440 minutes. For example, for those days that I totally didn't wear the device (Inspire 3), the values are 1440, 0, 0, 0, which sum to 1440. But there's still 30% of the data where the sum is less than 1440 (among them, most are greater than 900 minutes). I am curious that in what situations the sum of the 4 detected values can be less than 1400. Thank you!

Hi @new_developer 

Thank you for reporting this problem.   Let me try to reproduce the problem and investigate it.

Hi @new_developer 

To answer your question, the active minutes values do not include off-wrist time.  Therefore, it is normal to have a sum that is less than 1440 minutes.

Hi Gordon,

Thank you for the reply. I assume the "active minutes" you mentioned does not include sedentary minutes? My post title seems misleading too.

My data shows that when I am not wearing the device, those minutes are counted as sedentary minutes. This can be proved by the observation that in the days that I totally didn't wear it at all, 'minutesSedentary' is either 1440 or very close to 1440, and the sum of  'minutesSedentary', 'minutesLightlyActive', 'minutesFairlyActive', and 'minutesVeryActive' is exactly 1440. The data below are examples. (Note that in the first row, I didn't wear the device but put it in the bag for work, so there is some amount of steps even if I didn't wear it.)

.

Another set of data is when I was traveling and left the device at home. In these days, not only I didn't wear it, it is certain that the device didn't have any movement.

Then here is the question. What I am curious about is that, in some days, the sum of 'minutesSedentary', 'minutesLightlyActive', 'minutesFairlyActive', and 'minutesVeryActive' is less than 1440, as the examples in red below.

Thank you!
