I have wahoo ticker X. I started to use HRV4T recently. What bothers me are readings
- If I use Apple Watch 4, my HRV is always very low (cca 20ms) / I did not import data to HRV4T as the reading is very low
- If I use optical lense on phone (iPHone) i get HRV4T readings something like 6.5
- if I use Wahoo ticker X I get readings around 8.5
All mesurments were made at morning sequentali and multiple times.
So which data is corrent :)?
