Are the discounts fair? (Patreon)

I've been thinking about increasing the various discounts my patrons get, perhaps even doubling some of them. In the past I've tallied up the discounts and I'm not entirely sure they're "worth it" compared to how much my patrons are already paying per month. My goal was for them to serve both as an incentive and to offset the cost of patronage, as it seems that money is tight for everyone these days, though I still want to eventually reach my goal of making at least $1000 a month from art. Your thoughts?
