No, I don't think so. 3000 is as far as the meter goes, but that's not Max. Max is 4000 or 5000. (strangely, 4000 seems to lead to a better ending than 5000.) At 50%GR, that means 8000 or 10000. You can get 8000 by making every decision focused solely on gaining War Assets, by scanning every single solar system 100% and by having the perfect decisions (again focused on war assets) from ME1 and ME2.

10000 is impossible to achieve, it seems. I had 7900 and I did every single quest, had every system scanned, I just had a few minor decisions that cost me some War Assets here and there.

You sure about those numbers? I got around 6400 (total) and I got the good ending (where nobody on earth dies during the brief snippet in the endings). Is there a better ending I don't know about?
