I have an XL egg and have noticed that my cook times are MUCH shorter that most recommended times. Today, I made a discovery. The temperature measured at the temperature probe hole in the dome is almost 100 degrees lower than the temp measured just above my turkey at the very top of the dome. For example, the temp at the probe is 300 degrees and at the top of the dome just above the bird is almost 400 degrees. Which temp is accurate? Do I take the average of the two? My turkey is about 2 inches from the top of the dome.
