Hi all,
I'm hoping to play around with the API a bit, and was just wondering if it is possible to obtain quantitative error estimates (error bars) for the Charge HR metrics, and in particular of the heart rate. I could, I suppose, make my own by comparing with a chest strap, but presumably Fitbit has internally-collected measures of the actual accuracy. Unfortunately the docs provide no information on this matter, instead simply claiming that the band is "accurate".
In lieu of this, is there at least some information available about which heart rate ranges the band measures most accurately? It seems to me the accuracy is a bit impaired above 150 bpm or so.
Finally, is there any way to obtain my own band's raw HR data (pre-averaging)? I'd like to experiment with different averaging/smoothing methods.
Thanks!
