Players will very quickly learn the granularity. They'll snoop, remote
watch, or otherwise see a mobile "do" something, and then know that they
are safe for at least 15 seconds to do whatever they want before they need
get out. I've done this more than once with different games.

Better, but the problem of the same base granularity remains.

I'f you are wedded to the pulse/polling model for whatever reason I'd
instead tend to have a loop which iterates across all possible candidates
a say one N'th the intended action frequency, and randomly selects N% of
the candidates on each pass for activity. (Play with the numbers until
you like them) The intended result is that every (say) 3 seconds a given
object may or may not get evaluated, with the strong possibility that some
oblects will be ignored for extensive periods, and others hyper-active.
Tailoring your pseudo-random number algorithm can change the shape of the
curve here.
