Hi Mads,

that figure came from an interview I had with the makers a while back. They speak about it in some of their documents also — https://www.beddit.com/static/Beddit_Science_Leaflet_A4_HR.pdf

It seems like this figure is related to the heart rate accuracy as opposed to the actual sleep stage tracking — so it’s a little misleading. I’ll make the update.

Note also — this post is old. Beddit is no longer a product being sold or developed since it was bought by Apple.
