Most of the remaining variation is explained by one more dimension. Using the simplified equation, not only more properties of the tug-of-war model can be obtained analytically, the related numerical calculations will become more accurate and more efficient. But no matter what you position you try to argue for on what dimension, most readers will try to project your position onto the few "key" policy dimensions, asking whether your position is pro abortion, more taxes, more regulation, and so on.
