I was wondering if someone could tell me how critical temperature variances are? I am curious if say the temperature goes up to 234 or down to 220 if that will cause any problems. I'm guessing that a 5 or 10 degree difference isn't going to matter a whole lot as long as it is within that range. Is this a correct assumption to make? Right now my smoker seems to fluctuate from around 228 to 232 degrees.
