Totals - The default option, selecting 'Totals' from the drop-down menu updates the table to show the aggregate values for all the pertinent fields. Some fields, like efficiency and average CPI have fixed value types and do not update to match the current selection. Average CPI always measures the average CPI per call, while efficiency always reports a percentage.

Percentages - Changes all of the pertinent fields to reflect their value as a percentage of the whole. For example, select Percentages and the functions report updates the self time field to show the percentage of the total time spent executing a function's instructions.

Averages - Changes the statistical value to an average value per call for each of the functions or classes. As you would expect, this menu option is not available in the files and classes report types as files and classes are never themselves invoked.
