If you take "A Game Of Thrones" (the shortest book in that series) there are 298,000 words. At a rate of 1000 words/minute, that's 298 minutes; 149 if you're reading at 2000/min. That's more than 2 hours if you're at World Champion reader level, and you still wouldn't really be 'absorbing' the information contained on the page.
I don't really find "fast" readers impressive, usually for the point mentioned above - you ask them about the book and they don't know because they didn't actually read it.
