My sister asked the oven guy when he came to check the 2 ovens/the gas burner stove, and the grill that it is next to impossible to set a gas oven to the "correct" temp with the thermostat. They can "maybe" get it to 25 degrees, but even that is not likely, from what she told me.
I have found that the little trays (look like ash trays, but I know they're not since they are in the kitchen) work great set on the bottom rack and that gives the pan just enough lift to put it to the middle! I think these look pretty darn good.
