The real problem with measuring real things is that real things have infinite dimensions. You can only measure along a limited number of dimensions, and if you want to make a ranking you can only directly compare one (scalar) dimension at a time. So in the end you will always get overoptimization over those dimensions you are measuring, to the detriment of the other dimensions. I don't think there is a better solution than continuously changing the dimensions of measurement.
