In most cases with Patreon, the overwhelming members are free tier with the 1st tier being by far the most popular paid option. The numbers you see next to the videos aren't just likes. They are counted from likes and comments and maybe even reposts too. Tier 5 most likely has the most engagement too. So if we look at last month's tier 5, we see 179 next to it. There are 62 comments and an unknown amount of reshares. That means that at best there is likely around 120 unique patrons who interacted with the post and at worst (assuming reshares count towards the number) maybe even less than 100 interacted. I assume tier 5 is around 150-200ish subs.
