How do you know what the perfect spring rate is for a car? How do you know if the car is under or over springed?

Can you corner weight a vehicle and match the spring rate to the corner-in a 1:1 ratio? Would this provide a starting point? Or is this all just random guessing as to what is ideal?

Lets say the front corner weight of a car is 500 pounds. A 500# spring would compress 1 inch under the weight of the vehicle. As that weight is shifted additional compression would occur. Based on suspension travel couldn't you calculate an ideal spring rate per application?
