Yesterday I was smoking 3 racks of spares and two fatties. My BB has four shelves in it. I was using t seperate digital therms. One had a probe in one of the fatties and a probe monitoring the top shelf rack temp. The other two probes I had on racks 3 and 4, or the bottom two racks. I have tested these probes a year or so ago and they were accurate at that time. I noticed the bottom rack (rack 4) had a fairly steady temp of 190*. The next rack up (rack 3) ran around 220*, and the top rack ran a temp of nearly 270*! Has anyone had this type of temp variance with their Big Block? I had the control knob on High and all vents closed to the tab stop. I would have thought my hottest temps would be closest to the flame. The temp here in NE Kansas was lower 60's and a little breezy.
