It means there's a lower granularity of values, so less (re-)searches are
required to arrive at the score.  I have believed for some time that this is a
correct decision, because I don't have confidence in the precision of even
centipawn evaluations (much less the millipawn evaluations that Diep years ago
when Vincent based mtd techniques heavily).  I didn't know that Fritz actually
had done it, though.

The range of positional scores is relevant for lazy evaluation schemes, but I
think that issue is pretty well handled by Don Dailey's recommendation.
