The RuneScore total template is used to show the maximum amount of RuneScore which can be achieved. The total RuneScore of all 2,009 achievements together is 21,081.8. If an achievement does not have an individual page (yet), then its RuneScore will not be counted in this total until it gets its own page and this page is purged. The game unfortunately shows different amounts for both the total of achievements as well as the maximum RuneScore. Jagex is aware of this issue.
