Sounds pretty scientific to me!
Thanks for the additional info. My brisket cooking is still a work in progress. I feel like I improve with each cook, but to be honest I go so long in between I'm not really sure. But I know I've got the basics down.... fire WSM, trim fat, apply rub, put brisket on smoker, wait, get impatient, wait some more...
Anyway, the last cook I did I pulled the brisket somewhere around 185F to 187F. I usually start probing for tenderness around the 185 mark and go by that rather than the temp. But whenever I look online I hear that the sweet spot for brisket is (depending on who you ask) 195-205. Everyone enjoyed my last cook, but being that I'm always trying to improve, I think the next time I'll try to be a little more patient and see if I've been undercooking all this time.
