I usually get my 8-9 lb butts done in 10-14 hours depending on what temp I smoke at. Tomorrow I have a 3.8 lb piece I'm planning to smoke most likely around the 225-235º range and I'm trying to figure a reasonable time to put it on considering at least an hour rest at the end. Would it be reasonable to estimate getting to an IT of 205º somewhere around 5-6 hours?
