I thank member rivasp12 again for the lead pointing to these posting.
“Folks, no actionable information on your health is derived from HRV!”
I had already reached my layman’s conclusion that it was totally unreliable because it varied so widely as regards time taken etc.
My HRV tells me i should not binge drink. That arguably is actionable information. (Or inactional information)

Heart Rate Recovery (HRR) vs Heart Rate Variability (HRV)
“The Skeptical Cardiologist” Thinks HRR is superior to HRV in determining future mortality.
I agree because the HRV test is so variable, much more so than my recovery time to a given heart rate.
I have been using my heart rate recovery when doing short HIT workouts at the gym to determine when I was good to go for another one. The studies are for treadmill tests however and because of my ankle that would be pretty hard for me to do. Though I am not sure why the treadmill would be a better test in determining the recovery time from a given heart rate.

Here is a link to his site. He has lots of information about various medical devices such as fitness, heart rate monitors, wearable blood pressure monitors, etc.
