When the sensors cannot measure heart rate, the Forerunner 965 just invents numbers out of thin air.
This disturbs my attempts of precise training control. When heart rates are different than expected, I am wondering what's wrong during the analysis, until I figure that Garmin is just straight out lying to me and maybe the belt was not properly attached or it was not moist enough or whatever.
Is there a setting to stop the Garmin from fabricating numbers? Either record an accurate measurement or record "no data"? I cannot imagine that any serious athlete wants made up data in their training logs.
