The only answer I have is, it works for me. I live at 3600 above sea level in the High Plains. I don't have a thermometer on my PBC and don't use electronics. For whatever reason I stumbled on this combo (probably beer induced finishing out coal bags) and it works. I do use a Thermapen later in the cook on larger cuts. My first cook with these briquettes. BUT, I've got 36 beers, no responsibilities the remainder of today and the bride has gone to Dillards. Life is good. BTW- ribs and brisket are for later in week- grilled ribeyes and a green veggie of some sort for meal
