A little bit of experimentation is the key, Bob. I have seen BBs go 2hrs/lb at 225F on my #2, and then sometimes they take less time. With the Maverick, you will get a sense of where your #1 is averaging out when you set for 225. Pulling the BB at 195IT should be fine if you then double wrap with foil and let it sit in a cooler for an hour or 2, which will allow the juices to redistribute as well as increase the IT of the butt.
