How is sleep quality calculated?
-
@gkaempfer Sleep tracking is crap. It doesn’t reflect HR and HRV. Also it doesn’t count with changing to winter time. It shows 1h shorter sleep.
-
@HonzaS I noticed that yesterday. It’s a shame that Suunto offers too much “broken” functionality. It’s not so hard to fix issues like this these days…
-
@gkaempfer @honzas Daily sleep data 24-25.10.
It will show your heart rate. HRV Unfortunately no, HRV will be average in my opinion. spO2 off.
-
For me overall feeling, HRV and HR is all data I need.

Garmin (FR965) combined percentage of time in different sleep states, total sleep time, stress levels and how often you woke up. They actually presented a breakdown which was a nice feature.I assume Suunto is doing something similar based on how I see my sleep being scored. For me it seems Suunto has a problem judging light sleep vs awake state.
Your score is obviously wrong. For me I think the scoring roughly works, although I think some improvement of the algorithm would be nice.

How many of us know how we really sleep? I have no idea. All I know is that I wake up on the toilet and that’s it. If we don’t have data from the laboratory, we don’t know anything. What matters is the feeling of sleep…

I’m quite concerned about this topic regarding the new algo used accross devices.
I’m looking for a screenless device for sleep and daytime tracking, without having to wear a watch.
My Suunto Vertical 1* isn’t reliable at all when it comes to sleep tracking.
Does the Vertical use the same algorithm as the newer models (Vertical 2, Race3s)?If Suunto releases a screenless device but the sleep tracking isn’t reliable, I’ll probably skip it.

I believe even the best algorithm would only reach 80% accuracy which is a big step down from what we are used to with HR and GPS.I would tend to agree with previous posters that it is likely better to work off subjective feel or more integrated metrics like resting HR and HRV.
My experience with Garmin AI Coach was that it gave too much weight to sleep scores and flipped between - “rest day” or “go all out”.
Most companies would strive for one code base, i.e. implement a feature once and then include it in the device where you want to have it.
-
@MarTej_cz the number of times I yawn on my way to work gives me a pretty clear idea of how well I slept, much more accurate than any score you might find out there
-
@snow Feeling is the best measurement, as you say… In training, it’s just the opposite, when you don’t want to, the best performances are…
-
I don’t care much about the estimated sleep quality, I just want the damn watch to accurately start the sleep tracking. Im sick of the morning report saying I got 10.5 hours of sleep when in reality it was more like 7.

With my Race S sleep score is always between 72 and 88, regardless how well I slept. It is more of a random number generator.
With Garmin I had a lot more variety. Numbers between 30 and 99. Not that it always matches the quality of my sleep but more often than not it does…
