Data Dump

Back in March, I got a Samsung Gear S3 smart watch to replace my FitBit Charge 2.  I’ve been doing a lot more tracking, etc. with it than I ever did with my FitBit.  But until now, I haven’t really looked at the data.  Well, now’s my chance.  Here’s all of the health data I’ve recorded.


My data actually goes back to January – I assume that some data got imported when I did some syncs with different apps.  Here are my average sleep times for each month:

  • January – 7 hrs 26 mins
  • February – 7 hrs 47 mins
  • March – 7 hrs 56 mins
  • April – 7 hrs 0 mins
  • May (to date) – 7 hrs 2 mins

My average sleep efficiency recorded for April/May was 90%.  I’m not actually quite sure what “sleep efficiency” is, and whether or not that was a metric that Samsung came up with.  It turns out, it’s an actual number you can figure out yourself.  Here’s how defines it:

Sleep efficiency is the ratio of the total time spent asleep (total sleep time) in a night compared to the total amount of time spent in bed. For example, if a man spends 8 hours in bed on a given night, but only actually sleeps for four of those hours, his sleep efficiency for that evening would be 50% (four divided by eight multiplied by 100 percent).

So it looks like I’ve been sleeping pretty well, on average.


  • March – 8112 average daily steps; average distance 6.07km
  • April – 8247 average daily steps; average distance 5.63km
  • May (to date) – 8813 average daily steps; average distance 5.92km

I seem to be fairly consistent with the average daily steps.  My goal is 10,200 currently, and I’ve hit that 18 times (according to my ‘badge’ list – the last time I hit it was this past Monday).  The most steps I’ve walked to date was March 14th, when I hit 16,838 steps.  The previous record before that was 13,392.


  • March – 99 average active minutes
  • April – 103 average active minutes
  • May (to date) – 115 average active minutes

You can tell that I’ve been more active as the weather gets better.

Heart Rate

  • March – 46 bpm Minimum | 68 bpm Average | 200 bpm Maximum
  • April – 45 bpm Minimum | 67 bpm Average | 171 bpm Maximum
  • May (to date) – 49 bpm Minimum | 69 bpm Average | 177 bpm Maximum

I’m not sure how to analyze this data, to be honest.  Is that good?  Bad?  Looking at the average, specifically; I figure that the minimums/maximums will probably be outliers anyway (and the max would be recorded during exercise).

I did some brief research, and found a formula for figuring out targets for training at least.   Using that formula, my max heart rate should be 186-188.  So it looks like except for March, I’m well within that range and have some room to work harder.  I found a Livestrong article that suggests 60 to 100 bpm is “normal” for ages 10 and up.

So there you have it.  I’m interested to see how my numbers compare for June/July/August.  I anticipate that my steps / exercise will probably increase vs the comparable numbers for March/April/May.  I think that it would be realistic to shoot for a 65 bpm average as well.
