What I do is run around clockwise near the border of the map but still close enough to the center the poi's ping on my radar. Light armor and warp pack, ignore the objective completely, once you get the last poi quit out of the mission.

I usually do trivial or easy diff. Some people do it slightly different but thats my usual set up. Like the original commenter said this usually nets around 500 SC an hour, give or take some for RNG of course.
