Syncing HR watch/chest strap to Strava app -- is the HR sync'd perfectly along the route???
I use the Strava app and love it. Want to add the HR element. Knowing very little about the process, I'd think the syncing between the HR device (optical wrist or chest strap) would have to be live and real-time... not uploading it later to Strava.
Do the app and HR device need to be in real-time sync so the HR is in lockstep with every foot of the run/ride? If I am to upload the HR data later (which I see is the case for some of these watches), how it the route in the Strava app perfectly aligned with the data on the watch? i.e. at the 1/2 mile mark, HR at that exact spot was 130. Real-time vs uploading/syncing later seems to vary in results, no?
Thanks for helping me!!
