I see it this way; if the person has amassed a couple hundred edits in one single day, that's a cause to be suspicious, and it'd be worth looking into. If the 500+ edits were gained overtime, within a month or more (since I'm not quite sure how many edits the average user makes a month, that's just be spitballing), then it shouldn't warrant an investigation. I don't think they need to be "meangingful" so long as they aren't "rushed", such as just making minor changes repeatedly over the course of the day to build up the counter.
