The problem with comparisons is that you often don't know how exactly the moves
are stored in the book.
For example, a Fritz book tree is typically about 10 times as big as the
respective "original" file, judging from the conversions I did with the books of
Rebel 10, Genius 5 and Fritz 3.

BTW, Rebel's book is much smaller than the 16.8 MB you give. I think roughly
about 1/10th of that. CM6000 ditto.

CSTal 2 has about 510 MB, but no-one knows how many moves/positions it has,
which is the only valid number.
