Yeah, ST isn't too bad for 35-45. You'll get about 33% of a level every run, stays consistent as the mob xp continues to go up as your toons level.

If you're a skinner, you can loot/skin on one run and then do 4 runs w/o looting and stay just under the reset lockout. I guess if you're not a skinner you'd have to loot 2/5 runs to avoid hitting the lockout.
