I don't know how many chapters, since I don't read particularly fast. And I read manga along with novels. I know I read at least 3 manga chapters and 5 novel chapters on days where I am exhausted and should just go to bed instead but I want to read a bit. On days where I have lots of free time and no plans, I spend most of the day reading.
I almost never go a day without reading for at least one hour. Only one hour feels lacking though. 2 hours is okay, but 3 hours per day and the hungry ghost in my mind that demands stories is quite satisfied
Somehow reading through the forums slightly satifies it too, so if I'm on NUF alot, I don't have to read as much that day.
If a novel is good, and it's action type, yes I read faster. If it's good and non-action, I think I read slower to enjoy it more. If it's action but also pretty descriptive, I probably read a bit slower too.
Holy truck you're fast!
It took me a lot longer!
