Inspire 3 stopped tracking my heart rate on Saturday

[Stuckyville]

Nearly every day I ride my bike over the same 10-mile course, then log the activity to a spreadsheet, taking time, distance, average speed from my bike's computer.  Since getting my FB, I've added time spent in the cardio zone to what I'm tracking.

Immediately after every ride, I open the spreadsheet and enter the activity.  For the FB info, I scroll down to "heart", tap to open that.  At the bottom of the screen, under "This Week", will be an entry for the day.  Opening that will show how much time was spent in each exercise zone.  Except that on Saturdays there will be no entry, the most recent entry under "this week" will be for Friday.  Looking at the "weekly summary" at the top of that screen, the label for Saturday (only) is in bold, which indicates to me that it thinks there is something "special" about Saturdays.

The home screen summary shows a heart rate range for the day that is consistent with the fact I went for a ride, with the top rate at 122 BPM.

So what is special about Saturdays?

Hi, @Stuckyville , Fitbit gives you the option to start your new week on Sunday or on Monday.  It is possible (I haven’t checked) that depending on which day you have chosen for new week start your Saturday (or Sunday) entries may update a little later (or change a little later) depending on your settings.  Just a thought!  

To find out which day of the week you start on please go to your Fitbit app on phone or tablet.  On the opening screen please click on the small gear icon top right and then choose “Date, time, & units”.  On the next screen choose “Start week on” and maybe experiment to swap between Sunday or Monday and then see if a change causes any effects of the data report for Saturday.

My assumption (and expectation) that either way your info for Saturday will ultimately be the same.  But it is possible that it might temporarily look a little different if the switch over to a new week is Saturday at midnight or Sunday at midnight - which would depend on your setting for Start week day. (Short answer: Saturday might be special if it is the last day of the week, and therefore data gathering day.

@Julia_ 

For starters, it is set with the default of the week beginning on Sunday.

And, to quote an old cartoon character, "this just gets curioser and curioser."

On the "home" screen, under Activity - Exercise Days, it checked today (Saturday) as having had exercise.  And the only exercise today was my morning bike ride.

Immediately below that is says I spent 47 minutes on "Outdoor Bike", beginning at  8:09 AM, which is correct.  If I tap on that to drill down, the resulting screen is labeled "Mountain Bike".  It says the duration was 47 min 46 s, which is correct, but then says I had 83 "zone minutes".  Hmm.  83 minutes out of 47 minutes.  Then a chart of heart rate over time, and a breakout of time in each zone, with the zones being "Light", "Moderate", "Vigorous", and "Peak". These are different zones than those reported under heart metrics, with those being Fat Burn, Cardio, and Peak.

Going back to the home screen and drilling down on "Active Zone Minutes", it reports my time as being on a Mountain Bike.  Hmm,  Outdoor bike, road bike, mountain bike.  Whatever it thinks its using to make a distinction, it's not even internally consistent.

Back on the home screen and scrolling down to "Hourly Activity", it says 3 of 11, and indicates 8:00 AM, my bike ride.  The other two hours are 10:00 and 11:00 AM.  At that time of day I wasn't even wearing the FB . . Two active hours laying on my desk!

Did you know that peak counts as double for zone minutes?  And I think vigorous does also.

Yes, I had seen that, but I fail to understand the logic.
