[Unbound-users] how often can I call stats_noreset?

I've started implementing a Performance CoPilot* PMDA**, so that we can
collect all the metrics from "unbound-control stats_noreset" together
with other system performance metrics, and view the performance
numbers both realtime and collect historically. Example screenshot of
pmchart visualizer showing some live unbound and cpu performance metrics:

So, this PMDA is now running "unbound-control stats_noreset" every second,
which seems a bit excessive maybe, but is there any reason to be carefull
with how often we call stats_noreset?  Or are there any more efficient
way of polling these numbers if stats_noreset is unadvicable?
