In the range of 200-300 degrees, my drum can be 30-40 degrees hotter in the center compared to the edge installed analog with the 2.5" probe. I've read where others on this forum have seen as much as 50 degrees.
My drum temps seem to balance out on both the digital and analog around 300 degrees and above.
You may want to also minimize the amount of charcoal you use, 15 lbs. is a lot.
