Resting HR “floor”

I’ve won a pace pro now for about a week overnight for sleep monitoring and generally while somewhat more basic, I like the HRV recovery and the sleep quality feedback. One thing I noticed, though as compared to either a polar watch or an Apple Watch is that my resting heart rate seems to hit a floor of 50. On my Apple Watch a few times a week, my resting heart rate would read dipping into below 40. I guess I’m wondering, is there a setting on a COROS Watch that provides a theoretical floor to my heart rate?
