A rare perfect 100 sleep quality score! For some reason I feel more pleased with myself over something that might seem trivial than perhaps I should be. Prior to Withings making changes to the way the score is calculated, which was about a year ago, perfect scores were relatively common; this is the first such score under the new metrics, which have refined things somewhat to take into account not just the quantity of light, deep and REM sleep, but heart-rate variability and many other factors. I do not see it as trivial and, apart from anything else, it has introduced a feel-good factor into my morning.
