Nice article.

I did look at my sleep data a few years back when I had a Polar and noticed a drop in quality when drinking alcohol. We all know the impact of alcohol on our body and recovery, but visually seeing the impact (also with HRV) did make me stop drinking completely, with all positive results linked to it.

So perhaps as with everything, it's key to be aware but not to obsess over it.

In regard to the HRV app, what is the impact of sliders like sleep quality? Purely the advice?

And how to use the sliders? Should you use them as a all out or nothing? Because I only gradually move them as I never exaggerate scoring.

thank you Steven, I agree with you. Regarding the app, correct, the questionnaire will impact only the color coding and the advice, never the numbers. I tend to use the slides the same way you do, while other people might go all the way: as we always look at relative changes in your own data, it doesn't matter, it's more about how you do it (consistently) over time, so that trends are captured correctly. Your normal range for subjective scores might be narrower than for other people, but that does not impact interpretation (you can see it in the Pro website under Overview, if you login here: https://hrv4training.web.app/)

Great article, thanks! I'll be sharing this when discussing the shortcomings of wearable's scoring.
