Well, you could. I'm not big on the whole X amount of time for this, Y amount for that, etc. For pork or beef ribs I prefer to smoke (at whatever temp, it doesn't much matter) till nicely colored, then foil with a bit of liquid (I use juice reductions, sometimes mixed with stock reduction). I cook in the foil till done - perfectly tender. Never look at a clock as it is all about tender. (Nor do I use a therm. Meat can be tender at a variety of temps. Temps do not cause tenderness.)
When the ribs are tender I remove them from the foil and return them to the grate for a few minutes to firm up. I greatly dislike ribs that are sauced during cooking so I don't do that, much preferring to serve sauce on the side. On occasion, however, I will glaze with a glaze - not a sauce. A glaze will only take a couple or three minutes to set so after a few minutes on the grate out of the foil I will apply a thin glaze veneer, give it a couple minutes to set, remove, rest a few, slice and serve.
