This is about attitude , not specific techniques !
These are not electronically controlled stable temp smokers that cook 10 hours without tending.
These are imperfect, interactive, cookers that you learn the quirks & work with them.
Temps will vary, I'm happy with 215-290F between reloading.
A temp variation of 50F is common, from firebox side to smokestack side, don't sweat it.
You need to tend the fire, heck, make it enjoyable, a music player, a dog, adult beverages, a laptop or tablet to post on LTBBQ all make it fun
