I also use spead reading once in a while.
I can read realy fast going through large documents
To be able to find something quickly
I once got a huge document on my desk 3400 pages, and i had to decide if we would do that project, please try to read it.
To their surprice i fineshed reading and pointed them on the hard parts of it, they never thought anyone would be able to read the entire doc in just a few hours for the deadline.
