Percentages

When percentages are listed, they are relative to the total number of articles or dates that meet the criteria for that section (table) and are not meant to be compared between tables. For example, the "% Articles" for the "Dates in article bodies, per article" are calculated according to the total number of articles that have dates in their body (excluding templates and references.) Similarly, for the "Dates in templates, per article" table, only articles that have dates within a template are counted.

Also note that the percentages in the per-article tables will not total 100%, because there is significant overlap between the different categories — an article can have dates in both MDY_linked format and DMY_linked format, and will be counted in each row (but will only count toward the total number of articles once.) The percentages in the per-date tables will total 100%, because each date can only be in one format and so there is no overlap.
