The formula you've given for the Tournament Scores (log((n + 1) / r)) is the default Tournament Scores formula. The corresponding default Overall Score formula is (1-exp(-average(scores))) * 100. You can see this by pressing the "Edit Profiles" button on the Stats tab, selecting the Default profile, then clicking the "View" button in the "Create Overall Scores using formula:" section.
But, if you're just accumulating points, you don't need to provide any formulas. The "Points" column on the Stats tab will sum each player's points automatically.
