I do think ribs are a lot more predictable from a cooking time perspective, more so than a bulkier piece of protein like a pork butt, ham and certainly a whole brisket.While I can appreciate the sentiment, if you have something that holds a constant temp, times are usually spot on for ribs. Looser for pork butt but usually kinda consistent. I have not yet figured out the voodoo of brisket. I just do that in a slow cooker for corned beef.
