Subject: Book/No-book more data from a longer run

This is on the 2.2 GHz 64 bit computer (which had fewer problems than the slower
machine).  The first set is the raw data, and the second set has had all
duplicate games removed.

It seems that Fruit may benefit from a book slightly more than glaurung.  At
least, in the case of fruit, there is now enough data to say for sure that a
book does help.
