It looks to be in the middle to me. While we're talking about grate positions though, you know what I prefer for chicken or ribs if layed flat on the bottom grate and only using two levels? I use my spare grate, positioned on the grill strap bolts, which raises the bottom cooking level up a bit. It just seems to make the grates cook more evenly in relation to each other, and gets a little more heat and smoke to the middle of the bottom cooking level.
