Players earn points in tournaments. If you want to create points, use the formula I provided in the "Points for Playing" field on the Game tab. You'll have to do this for each tournament (that is, load each saved tournament, set the Points for Playing formula, and save the tournament) and going forward you'll need to make sure to set the formula in the Points for Playing field each time.
When you set the formula in the Tournament Score formula field of the Stats Profile, the formula is creating a "Score" value for each player for each tournament. So, on the Stats tab, it won't affect the "Points" field. The Points field is the sum of the points the player earned in each tournament that was found when you press "Refresh Stats".
You never said what you wanted to do with the values over a series of tournaments. The Overall Score formula can sum, average, or otherwise manipulate the Scores to arrive at an overall value for each player. To make the Overall Score value a sum of the Scores, set the Overall Score formula to:
sum(scores)
