68-70 smithing in 45 minutes...
74-76 magic in about 1 hour 30 minutes.
Now it's the 2h:18m mark, and I'm 71 smithing with 52k xp left, and 77 magic with 128xp left.
Also, I'm making about 250gp per bar made. 2500 x 250 = 625,000
Not to mention I've gotten 550k xp in those 2 hours and 20 minutes. Awesome.
