For many wikistats tables producing monthly metrics seems over the top, given that this would result in about 150 lines and growing. So for a long time a concise format is used on many tables: monthly metrics for the last 24-35 month, (at least two full years, always start with January), and quarterly metrics for the entire history of the wiki (again starting with most recent 'quarterly' month: Jan,Apr,Jul,Oct) This was not so intuitive, so extra headers now explain this explicitly. See e.g. http://stats.wikimedia.org/EN/TablesWikipediaEN.htm#editor_activity_levels
