I use Coros HR armband which has 38 hour battery life, so it is not unusual to run out of charge in a middle of a run if I forget to charge it.
Today the sensor has died in the middle of the run, so obviously the HR data has stopped being captured. That is understandable and not the watch fault. But by the way, the watch didn’t warm me that the sensor battery was nearly dead in the beginning of the run. That would be helpful!
However I was really hoping that that I’d be able to use rTSS for the accurate TSS data which shouldn’t depend on the HR data, right? Surprisingly, NGP data also stops at exactly the same moment where HR data stops, so rTSS ends up being nearly the same as hrTSS. So I still can’t capture the real effort TSS. Unfortunately my power zones are not setup properly so I can’t use pwTSS.
Furthermore, a bunch of other pace derived metrics also stop at the same moment - Heat Adjusted Pace, Wind Adjusted Pace, Real Effort Pace.
What NGP and all of these have to do with the HR data? If this is a bug, please let the dev team know.
