That's not the point.  I can most likely type as fast as anybody I have
ever seen.  You can ask participants at previous ACM/WCCC events where
I played about my typing.

But this isn't about _typing_. It is about _analyzing_.  It is _easy_ to
type say a couple of thousand moves per hour.  But that is _all_ you are
going to do.  What about checking the positions?  Catching things like
an obviously hung piece due to a typo in the stuff you are copying?  Etc.

Preparing a book requires a lot of analysis, just like a human does when he
prepares something to use in a tournament.  And doing 2K moves an hour means
_no_ analysis is going on to any degree at all...

For years I have played blitz chess with Cray Blitz and Crafty.  I put
5 minutes on _my_ clock and have at it, playing against humans.  I type
the moves in, make the moves on the board, and press the clock.  And I
have _never_ lost a game on time in under 60 moves, and have played _many_
games that go over 100 moves in that time limit.  IE I know how to type
chess moves myself.

remember that we are talking about a "custom book".  Not just a big book
typed from Informant or whatever...  that is the key.
