I’m no Doctor Nate but I believe that 80 for the diastolic is at the maximum end of ideal.
99/60 to 120/80 is the ideal range. I’ve also been led to believe by a Doctor friend of mine that it is the diastolic number ( lower number) that’s the most important.
My BP usually sits around 100/60 with a 52 or so BPM.
This was taken a couple of hours after riding Antelope so my HR was still elevated…
