I see where on these posts people are decarb'ng before using the MB2. Is is that you don't trust the decarb function built into the machine? ...because I don't. It's my understanding that you need to decarb at 240f for at least 20 mins to fully remove the acid. Since boiling point on alcohol (what I use) is at 160f, I use that setting for 8 hours. Then I transfer it to an induction burner at 240 until it reduces. It works for me!
