Vivosmart 4 vs vivosmart 5 stress accuracy

I know it has been discussed before but I would like to understand which device should I trust more for stress measurement. If I go by vivosmart 4 I have a body battery score of 100 at the end of an intense work day. If I go by the vivosmart 5 I have a body battery of less than 10 and no resfull moments. Since these are polar opposites. Which one should I trust more? Thanks! 

  • I would not put much faith in the Body Battery metric telling me anything usefull on any watch. But in this case the VS5 may have a "newer" method of calculation. And yes, there are lots of post on the Stess measured by the VS5. Who knows? Garmin will never tell us which one is more trustworthy....
