Nope, no power draft.
It turned out great. Temps started to drop in the last couple of hours, and I had throw more coals in. Cooked it to 205 internal. I've cooked brisket three times before, never to 205, and it always turned out tough. Most of the time the lid was running around 240, but dropped down to 225 for a while before I added more coals to get it up around 240.
This time it turned out perfect and has honestly been the best BBQ I've cooked in the year I've had my smoker. I've done a lot of que-ing in that time and I'm a pork kind of guy, so I was very pleasantly surprised.
I've seen butts and brisket get up to high temps pretty fast, and then plateau forever while the magic happens. I really only worry about internal temps when I think my timing is off (I don't always allow for the maximum time) or it's real low after a long time (only happened once, probe was touching the bone in the butt). Otherwise, I'd say try not to get too worked up over internal temperatures, it's going to vary a lot from cook to cook.
