Low HR alert not low enough

Version 6.00 of the software added an alert for abnormally low HR.  However the lowest I can set this alert is 40BPM.  “Unfortunately” my resting HR is around 37 BPM so having a HR lower than 40 BPM is nothing strange for me. Why can’t we set the limit at 30BPM?  I’m sure there are tons of people out there with the same issue.
