It would not be wise to calculate the average of two elements, when the units and scales are different. For instance, how can the QPR Metrics take the average of sub-elements if Gross Margin % uses the unit "Percentage" while the Operating Profit uses the unit "1000 Dollars"? The answer to this is that the scorecard formula should take the average of the elements' range values.
