As far Smokin Joes numbers go I believe he is right on track. I cooked this weekend for a church. We fed about 100 people, and I cooked 14 butts. There was at least 6 butts remaining. So the estimate of 8 butts is perfect. They did not go to waste. lol They provided the sides so I can't speak to that. Good luck!
