AZEO is overrated on this board IMO and is a niche technique for specific situations, not something you need to do as a lifestyle. But you could do it for any length of time, as long as you pay attention to statement closing dates.
I have a different "niche" lifestyle. I am one of the few that doesn't believe in auto-pay. So my AZEO game is to make sure that my minimum payment due is "0". Except on one card.
