The Active/Stationary and Active Hours features are not necessarily using the same data. Active/Stationary is based off of the minutes of activity, whereas the Active Hours is based off of step count for the number of hours you have chosen to be tracked.
Example: Let's say I set my Active Hours for ten hours, and I manage 10,000 steps in those hours. I'm not a robot steadily logging steps at an even pace for the duration of ten hours, so my step count will not be evenly dispersed in that time frame. I might do a workout and log 4,000 in 45min, slowly log 3,000 throughout the rest of the day, before I do an evening workout of another 4,000 steps in 45min. So it would look something like this:
Hour 1: Active 50 min, 4250 steps *
Hour 2: Active 2 min, 150 steps
Hour 3: Active 10 minutes, 400 steps *
Hour 4: Active 5 minutes, 400 steps *
Hour 5: Active 25 minutes, 900 steps *
Hour 6: Active 5 minutes, 600 steps *
Hour 7: Active 0 minutes, 0 steps (I have a long commute home?)
Hour 8: Active 0 minutes, 0 steps
Hour 9: Active 10 minutes, 250 steps *
Hour 10: Active 48 minutes, 4050 steps *
* = I hit the 250 step goal
10hrs = 600min; I was active 155min out of a possible 600min for those 10,000 steps. That percentage is 25.8% Active and 74.2% Stationary, even though I hit the 250 step count goal 7 of the 10 hours.
That means that I was not active most of the day, even though I may have hit most of my Active Hours of 250+ steps. This is what the Active/Stationary percentage is.
The Active Hours feature exists to make sure you're still moving around at a bare minimum each and every hour. The Active/Stationary feature exists to show you the proportion of how those steps equate to your overall activity throughout the timeframe you've chosen.
Hope this helps! 🙂
