You can define up to 5 Overall Scores formulas. By default only the "Overall Score" column is displayed, which shows the results of the Overall Score formula. But you can also define an Overall Score 2 formula, an Overall Score 3 formula, an Overall Score 4 formula, and an Overall Score 5 formula. Those will show up in the Overall Score 2 column, Overall Score 3 column, Overall Score 4 column, and Overall Score 5 column, respectively. You will need to enable those columns. To do that, press the Preferences button on the Stats tab and select "Edit Columns".
