@GiPFELKiND thanks a lot.
I exactly understand your point and that is clear for me that HRV depends on several factors and individual per persons.
What I’m curious on is the pattern that other can see similar or not.
I’m asking this because the relation I read about between deep sleep and HRV. In my case completely the opposite logic happens.
As I’m doing whole reviews by sport doctor, who hasn’t find problem, this surprised me. Maybe there is something which misleading the algorithm, what can prove if others experience the similar pattern like me.
