The reason I am disagreeing is because it's flawed to think of all meats in terms of "X hours per pound". Quick question, you have a 4lb piece of meat that is 8 inches long, 5 inches wide and 1 inch thick. That's 40 cubic inches of meat. I have a 4lb piece of meat that is 4 inches long, 5 inches wide but 2 inches thick. BOth pieces are 4 lbs and they are both also the same 40 cubic inches of meat, one is just twice as thick and half as long as the other.
Question: If you stick both pieces of meat in a smoker and cook them side by side, will they take the same amount of time to cook ? If not, which one will take longer and WHY ?
