I'm with your hunch that my Pebble Time is calculating the average twice
For the first few days of the past week, I've been checking the
averages three times a day but only well into the afternoon, and the averages stay unchanged until the next expected recalculation (except on sunday when a nap was taken, the average recalculated itself).
When I do a check for average:
Morning before 12nn (every day)
Between 12nn to 1pm (only the last two days)
Afternoon between 2 to 4pm (every day)
Afternoon after a nap (on sunday)
Late night just before I sleep (every day)
For the last two days, I've been checking out the average around 12:30pm (and again during the rest of the day). On both those days, the averages differ between "before 1pm" and "after 1pm". The second average that I get AFTER 1pm stays unchanged until the next expected recalculation.
Day Time of check Sleep Average Remarks
Friday Morning 7h 20m
After 1pm 6h 17m
Saturday Morning 4h 47m
After 1pm 5h 12m
Sunday Morning 9h 19m
After 1pm 4h 58m
Evening 4h 15m Average recalculates after a nap.
Monday Morning 8h 20m
After 1pm 4h 50m
Tuesday Morning (2h to 3h) Missed it, probably 2 to 3 hours.
After 1pm 4h 31m
Wednesday Morning 8h 11m
12nn-1pm 5h 3m No naps but there were two averages.
Afternoon 4h 20m "Today's sleep" still read 0m.
Thursday Morning (6h to 8h) Missed it, probbaly 6 to 8 hours.
12nn-1pm 3h 56m No naps but there were two averages.
Afternoon 2h 28m "Today's sleep" still read 0m.
I'm not having trouble or problem with this, so please don't take this as such. I'm just reporting the data as a beta tester and hoping this could be of some use.
