it depends. I don't like to do the grate because if you are in the hot air coming around the bowl, temps will be high, and if your probe is too close to cold meat, it could be too low.

Mark didn't mean the therm was wrong, just the location. Dome temp can be different than cooking temp, its well established.
Like you said the key is knowing the cooker, and being consistent.
