Temps are unreliable as a determinant of done because temps neither determine nor indicate done. If cooking at high heat, internal temps can rise very quickly but this only means the meat is hot, not that done is nigh.
Done means tender. A probe inserted into the brisket will go in effortlessly. Temp has nothing to do with it.
I think briskets taken to tender are best rested, merely tented, for 25-30 min. For holding, I do the same thing
then wrap and cooler or, if I know I will be holding the brisket, I pull it when it is not quite done, drain most juices, then immerdiately wrap and cooler.
Tom, I foil at 2.5 hours, give or take 10. A recent cook is described
here.
Enjoy your brisket Robert!
