Inaccurate data for many athletes with low resting heart rate

[Incog5]

"The data is filtered between 0.8 - 3.0 Hz (48 - 180 BPM)"

Can the lowerbound of the date filter range be lowered to ~40 BPM, or is there a way to manually adjust the range, since many athletes are can fall in this range.

Would be nice to have an adjustable range, say you know your heart rate is ~45bpm, you can specify the filter range to be from 40 to 50
