Oh god. The blind faith in reductive, objectivist, rationalist meritocracy that somehow "everything can be measured perfectly" and "whatever happens is completely unbiased as proscribed by a black-and-white, mechanical formula". No, sorry, that's insufficiently holistic in accounting for intangibles and supportive effort, and more of a throwback ideology that should've died in the 1920's. Some degree of discretion is needed because there is no shortcut to "measuring" performance.
