It’s best to use time as a guideline, however temp is the real marker for completion. Since it finished at 204, it was on the mark for when you would normally pull off to rest.
the recipe doesn’t have another crucial element, which is towel and cooler rest. Once you reach the magic 203 or so, pull from the T, leave the foil/butcher paper on and wrap tightly in towel(s) and put in a cooler to let it rest for 1-2 hours. This part is essential for letting the juices recollect and settle down. I’ve left mine in a cooler for fours hours before and it came out juicy and still hot enough to burn your fingers when pulling by hand.
The tried and true method:
225 with super smoke until 160-165
Pull from T, wrap in foil. Add any beer, juice, cider, whatever you want, if desired
Continue at 225, turn off super smoke until internal temp is 203
Pull, wrap in towel, put in small cooler to rest for 2 hours.
BTW this approach is also reliable for brisket, except for the towel and cooler. Instead, I take it off and let it rest for 25 minutes at least before carving.
have fun!
