In this note we compare and contrast arithmetic and geometric share-weighting aggregations of ratio expressions (i.e., relative scores) and we provide conditions under which they result in approximately the same value of the aggregate measure. We also provide some comparative empirical results about the differences among the suggested alternative aggregate measures.
