I Have been running lid to top grate test on my WSW for the last 5 smokes and found something interesting..

I was getting an average of around 17 degree hotter on the great than the lid thermometer. The test were done with the meat placed right on the great and center of rack. I did 3 test like this and got good readings of 17 degree average.. On my 4Th test i smoked  a chuckie it was placed in a 9x13 disposable pan and it was placed in the center of the rack I was getting a average reading this time of 40 degree difference from the top grate to the lid(hotter on top grate). I was confused why such  a difference when the other 3 smokes were just about spot on to each other. Well i go thinking the only thing different was the disposable pan so i went a head and finished the smoke. this past weekend i did another chuckie same way as before in the disposable pan and placed in the center of the great and again i was getting  around 40 degree cooler reading on the lid. The next day i did a chicken no pan just put right on the grate in the center and i was getting around 17 degree cooler reading on the lid thermometer just like in the first test smokes..

           So what i gather from this is the pan must be deflecting or blocking the heat from getting a good read on the lid  thermometer the only thing that was different was the pan.

 Test was done in a WSW 22.5 using a clay saucer.. the smoker was in my smoke shack  so weather was not a factor.. A BBQ guru was also used...
 
Yeah.... people have a tendancy to forget that air (and the heat it carries) do not always flow in a straight line from point A to point B. I have had hotter temps on my upper rack then my lower rack lots of times, due to the heat being deflected by the water pan, up the sides, then hitting the dome and creating a whorl that swings back down and blasts the top rack with heat. Then you start putting foils pans in that mix and the airflow changes yet again.

Nice break down TYO! Always nice to see what other folks are getting for temp variations.
