I got my new Body Cardio (Europe) and being curious about my shiny new scales, took all 5 measurements of Pulse Wave Velocity on the same day. 2 measurements when I first opened the scales, and another 3 measurements after coffee and breakfast. Got a reading of 6.1 m/s and "normal" vascular age.
Now I'm using the scales more carefully by measuring the same time each day in the same conditions.
Second day, got 6.1 m/s again.
Third day, 5.8 m/s, which was a surprise -- though a nice surprise at that.
What I'm wondering, is whether my impatience on that first day has had any negative impact on the quality of the readings I'll get going forward? And that could explain the jump on that third day? Should I reset to clear out my less than ideal initial readings?
Or does it not really matter, and it's better just to keep measuring every day going forward?
I suspect that only Withings technical people know the answer definitively -- but I figured I can't be the only one to have been impatient like this, so hopefully they will answer this question here and then it can help other users too :)
