@tomkindlon@disabled.social @mecfs@fedigroups.social SInce half a year after the first crash, a friend of mine uses the #Garmin Venu 3 with #HR monitoring and HRV and alarms, 'cause he didn't trust his feelngs, just the facts. For pacing essential. Connected it to #influx and #grafana for a deeper view. Tried it with #Apple, but they measure the #HRV not at night, but over the whole day with some #algorithms. Additionially he has the data from 3 yrs. #withings #scanwatch without HRV measurement.
