Jorgenwest already tried to help you on this. And the original posters point was on the same thing. I'm not sure how you got on this tangent, but it's a strawman. No one doubts that if you are given 5 x 2 you'll get 10. Of course that's objective. But it isn't whether 5 x 2 is objective or subjective, it's the question of whether it should be 5 or should be 2 and the decisions made in that regard. What's subjective is deciding it should be 5 or should be 2. What you decide to incorporate and how you weigh it is an act of choosing what is most important. That is, by definition, subjective. Now, you can have strong reasons for doing so. You can test it and find the results in line with what you are trying to measure, but nonetheless there are elements that are subjective. Hell, on WAR alone we have multiple ways to calculate it based on what different places choose to weigh. That doesn't eliminate them from being useful, but it pretty much squashes the "objective" argument.
