Before the most recent nerf, I was able to get about 54.7M isk/hour using a Nightmare to run missions with an alt in a Noctis following along salvaging simultaneously. Of that income, 42.9% was bounties, 20.0% was LP, 4.9% was drone alloys, 15.1% was salvage, and 17.0% was loot. I'm currently under a wardec so I can't re-run the numbers right now, but the worst case is something like 45.4 M isk/hour. Realistically it will be higher since some valuable loot still drops.This tracks pretty well with my experience, except my salvage number tended to be higher. That might just be luck of the draw, though. If you're at all interested in this topic, I strongly recommend going out to read Steve's blog post on the subject.
Now we need an updated version of this post for May/June 2012. Hint hint.
Thanks for your comment, Steve!
