i dont think he used ET only. In my opinion you cant break the 150-180k mark with ET even if you edit all day (weekly). The ranking should be limited. As example, there are the mmorpg's, when you start, you cant go and kill a level 100 monster, you have to kill the low level ones. I mean, people who are experienced, get to earn more points than newcomers. As the newcomers get formed, they are allowed to earn more points.
That would be cool in Waze, if you are a 600k map-edits editor, you should have an earning %, which is higher than someone who got 50k. Not sure how fair that is, but looks nice to me.
