Unsure. I read in fits & bursts. For the tiny fandom with rarepairs, I can tell you I've read every single one, even when I haven't liked it. When you've got only 10 fics, beggars can't be choosers. For massive fandoms like TFA? I get pickier. I'd say probably my average for a big fandom is 40-50 fics tops?

Unless I'm actively in the mood to make a rec list, I don't keep track. I also don't have an ao3 acct so I couldn't give you a real # anyway
