I've been using resperate for about three months, I have seen a drop in blood pressure.The user manual suggests that going below five bpm might be counterproductive.
I have been clocking in at 4.8 bpm's at the end of each session (this will vary a little, 4.9; 5.0.but usually it's 4.8). I am just following the guide tones, not trying to hit a low number and I'm not straining.

For most of the session the bpm is above five, but it's gradually lowering. I would prefer not to concern myself with staying above five bpm as that would actually take some effort at the end.

Most sessions last about 13 minutes in the therapeutic zone, with maybe the last two or three minutes under five.

Since I'm not trying to reach a low number, I'm wondering if I should just carry on, and not worry about ending up under five bpm's.

Any suggestions or tips? Thanks, Jocko
