you shouldnt really use it
That's the point, reading one word at a time doesn't make any sense, why would you want to do it? If you don't read aloud, reading multiple words at a time is a natural way to read.
joe states its jack that anyone can run 100m under 10 seconds, because he himself barely runs them in 15.
To read a few thousand pages a day - ofc it's douable. To
study a few thousand pages of legal acts and commentaries? Nah.
PS. "ofc it's douable" - though probably not by me. I've read in one day a few quite long books, The Da Vinci Code, last 2 Harry Potter books, among others, but even 2 thousand pages in one day would be out of my reach I guess. But there're faster readers ofc.
