I think 225 is too low. Most recipes i have read call for 240 for the pork butt. I wrap after five hours typically between 150-160. The meat i have produced is really moist and juicy. I watched the bbq pitmasters and they went to 250 to 275 for pork butt.
I would agree with your statement and if what you are doing works, keep doing it.
But at least with my #2, this baby runs hotter than I thought. I keep notes on everything I smoke or cook, it makes it easier to keep turning out great results.
Take a look a the chart below and you will see what I mean when I say my #2 runs hotter than the knob setting.
