I have the high abnormal heartrate alert set to 100 BPM. I have a condition that causes my heartrate to climb when sitting or standing which is a major reason for purchasing the watch, to catch these instances. I've had multiple instances where my heart rate was in the 120s and 130s but the watch never alerted. In fact, it has never alerted. If I'm merely standing or walking around as when cooking, does it think I'm active and that's why it's not alerting, or is there something else going on? Is there some what to adjust what "inactive" is?
