There appears to be a setting for an interval for heart rate zone notifications. However, while out on an activity, the device seems to be processing multiple notifications with wildly different zones. I was curious if these are queued messages that are all being announced back to back. Overall it's incredibly confusing, if they're meant to represent some form of average / out of target zone message. I'd suggest having the announcement at least sound different, and/or only allow ONE notification per interval.
