The four numbers that matter more than the chart
Pull temperature. Brisket, pork butt and beef ribs are done around 203°F when a probe slides in with no resistance; ribs when the rack bends and cracks; chicken at 165°F in the breast and 175°F in the thigh; turkey pulled at 160°F breast and rested to 165°F. Everything else is on the chart.
The stall. Between 150°F and 170°F the temperature of a big cut stops climbing, sometimes for hours, because moisture evaporating from the surface cools it. Wrap (foil fastest, paper for bark) or run 275°F+ to shorten it.
Rest. An hour minimum for brisket and butt, and two to four wrapped in a cooler is better. Twenty to thirty minutes for turkey. Ten to fifteen for ribs and tri-tip. Sear tri-tip and prime rib after the rest, not before.
Start early. Plan on the high end of the range plus the rest plus a cushion. Finished meat holds for hours; unfinished meat holds for none. The calculator does this arithmetic backward from your serving time.
