The pictures show the best part, everything looks great! I like the graph idea, you can really see what's going on! The most challenging smoke was my second one, 2 shoulders on the top, small brisket in the middle and four chickens on the bottom. I wasn't expecting everything would be done at the same time lol. You bring up a good point I never thought about, meat on the bottom taking heat from meat above it but it makes sense! When smoking two big meats, I will definitely take a look at switching racks around, good point!
