I imagine there’s more than one way to skin a cat.
For example, that’s not how I smoke ribs: I fire up the smoker and while the fire is starting I peel and rub the ribs (~.5 hrs until the fire is ready), put the ribs on 1.5 hrs 275-300°F, add basting liquid, double wrap them in foil, back on for 1.5 hrs, then uncover and back on not more than .5 hrs.
3.5 hours max grate to plate. Basta.
