The previous version had each column's difference from the
previous.  The new one had eacho column's difference from the
first column.  (Also, there are differences in what "after"
means. ;-)

Here's the "each-relative" version.  It sort of depends on if
you want to see each incremental change or the net overall change.

Thanks,
Mike
