THAT mammoth chapter, how long do people take to read it?

So, I see a lot of comments about folks not reading The Last Battle at night if they have work/general life responsibilities the next day, and it got me to wondering how long it takes everyone to read it.

On my last re read i timed how long it took me to read the chapter, and it was in the region of 2.5 hours. I know I'm a skim reader (which is awesome because I notice new things/things I'd forgotten on every re read) but I'm super intrigued to see other people's times. (My only other reference point is that the audio book version is like 9 hours or something crazy like that)
