There's a million different ways to get to the same result...to each their own. I honestly don't care...I was simply asked to weigh in. However, to your point regarding cooking maintenance...I know how to manipulate fuel, heat, and airflow and the relationship between temperature and weight so I can leave my Big Green Egg for an all day baseball tourney, play a round of golf, go fly fishing for the day, etc, etc...and never touch it. And no, I don't use apps, temp probes, a fan, etc. But i'm not going to try to convince anyone what to do as long as it works for them. It's futile. Happy cooking.
