Not all that differently. The last I did, iirc, went jusu under two hours for the smoking period, till they reached desired color (I Minioned the start with ~25 lit, as usual), and maybe 40 in the foil to hit tender. I put them on the grate unfoiled for a few minutes to firm, applied a thin veneer or transparent glaze, and let that seize for a couple minutes; done. Right around 2:45 total I believe.
Depending on how you start and how long come=up takes, timing can vary. But if you go by visuals first (foiling when your ribs hit a nice rich color), then feel (cooking n the foil till a probe inserts between the bones effortlessly), there is little room for error.
