I think you did the division backwards. By my math that's 1.8 days per book. I'm guessing OP reads pretty fast, and 1-2 hours per day spent reading isn't outside the realm of possibility. I would probably read 2-3 times as many books, except I'm a fairly slow reader and since I read for fun I have pretty much zero interest in reading faster.

Yes, this. I do read quickly, and I typically get 2 hours or so a day to read.

FWIW I don't read slower when I need to absorb serious content, but I do reread repeatedly -- flipping back and forth to make sure I understood the argument, critiquing it in my head, and so forth. Pleasure reading doesn't get that treatment unless I catch the author doing something egregious.

Haha that makes loads more sense, thanks!
