Patreon Organization (Patreon)

Okay this is another thing I've been thinking about and I wonder if Patreon is better suited toward people who produce context weekly/bi-weekly or monthly or what have you. Producing content 4x/week means that the "minimum" I have to charge is both really small and difficult for a potential patron to get a handle on--do they have to do the math in their head? Can they be sure that they know exactly how much they're pledging per month? What I'm saying is, do you think it'd be better if I just forewent charging per item and instead charged by the week or month so the pledge amount is easier to handle?
