All good, you don’t have to believe it.
Ive had a Polar watch, Garmin edge 500,800,530, 3 different Chest straps, Garmin vivomove HR, used my wife’s forerunner and a had a doctor comment when i was younger before i had surgery say “your the kid with the low HR”,
so not new to me in anyway, just investigating and trying to learn about how my body works.
