Your story "Reincarnated as a… Completely Average Person?" appealed to a certain demographic, that being Light Novel readers. LN readers love their isekai. And usually trending has a ton of isekai. It's like a person selling cold water in the middle of Arizona, of course you're gonna buy the water, same goes for ScribbleHub readers. Then "I Don’t Know but it Seems Like I’m a Deer!" got the attention of the readers you had from RAACAP, since it's in the isekai genre. But I could be wrong.
If you're making $17 a month through Patreon then I would say you're doing well. I haven't made a cent. That said, I haven't really given into the True Isekai trope nor have I written any smut. Seems like that is what gets you the big bucks and big readers here.
