I am a new owner and have to say that in our first 5 cooks, the results were terrific (except for one user error). This may be my best appliance purchase. I am planning to make baby backs and st Louis simultaneously at the same temperature. I gather from reading that the baby backs take less time. If I start the baby backs an hour later than the St. Louis should they both be done at approximately the same time (say 5-6 hrs for St Louis and 4-5 for baby back). Anyone have experiences to help?
