Good read, But 18min per heroic is damn fast using the LFD tool. I remember doing the math on a heroic LFD run of Nexus and walked away with 1626G from that one run, but it took a little over a half an hour killing, looting, skinning, paying for repairs etc. The number is a bit higher than normal because it was the first run so I walked away with 10 frost emblems as well.
