Smoked brisket - session #0.1

I want to make smoked brisket using my wood-pellet grill. I found a recipe by Traeger.

I reviewed the recipe making sure that I understand it. It looks fine.

I thought of an improvement too. The recipe calls for garlic powder. I recall my mom adding garlic cloves to a piece of meat by stabbing the meat with a knife and inserting garlic cloves in the holes, just deep enough to be flush with the surface of the meat. I think that will work fine and I think it will produce a better result than using garlic powder.
