I prefer the old method.  A hundredth of a pawn is fine for describing the value
of a position.  And if there is a direct mate, then the dm code should be used.
Having to parse new formats for something already adequately described is not
optimal for me.  And especially the case when one field has more than one method
of interpretation.  Maybe others will like it, though.
