Two thoughts about sleep tracking. The first, I think my Versa has passed the sleep tracking test. Last night I was up at 5 AM, actually went downstairs and walked around a bit, and then went back to bed. I has hoping for at the best a detailed sleep log until 5, and then a simplified log for the rest of the night. What I got was a fully detailed sleep log, with the 5 AM walk around counting as awake time. Nice. Only two issues. First of all, I was lucky when I called support because I got someone who knew what she was doing. She took me through a whole bunch of syncs and reboots, and at some time had me change the sleep sensitivity to Sensitive. It works.....IF I use the Layers clock face and only the Layers clock face. If I change it, even to one that was designed by Fitbit, no go. For the life of me I cannot understand this.
Second, I was thinking about wrist size and wrist shape. I have a pretty small, bony, wrist, about 6", and have always worn the small band on my fitbit products. My Charge fit the worst, with a large gap on either side of my wrist. The Alta fit the best. The Versa' underside does lie flat on my wrist, but there is a bit of a gap on each side. I imagine other users may have bigger gaps, or maybe no gaps at all. I wonder if how the device rides on your wrist affects heart rate and thus sleep stats. Although, the Charge, which fit the worst, did give me pretty accurate sleep stats. Go figure.
