It is absolutely not average. 200wpm would give ~22 hours. In this crowd, I can imagine 10-12 hours would be feasible (especially if you skip/skim the occasional boring paragraph). Anyway, who needs retention when you get to announce you read a 1000+page book?

When I said particularly fast, I meant for a regular book reader, not an average person. I'd compare it to touching your toes: being able to do it doesn't make you an athlete, even if the average fat slob like me can't do it.
