Looking at the charts, the max hr for the activity vs the max hr for my daily stats are different, so I guess the display is showing the data from the optical sensor. Maybe the data looks different as its sampled less frequently?
Only asking as my hr flew up to very high (190+) midway through my gentle run (around 6/km, I'd expect maybe 150bpm) today. Thought you it was the hr strap playing up but now I'm less sure.
