This might be useful for dialing in a new car before its maiden voyage, but keep in mind having the same rise rates on a stationary table isn't always ideal on the track.
Where this would work(maybe what this is about and I missed it) is duplicating something that works on the track for you, on a different car.
Feel on the track, flight over jumps, things like that...número uno.
There are so many compromises.
What is the goal of this process?
I agree with your points. To answer you question though, it gives a known and measured reference point. I personally test various sets of springs so that I know which groups are balanced. That way if I need to stiffen up the entire car, I know which group will provide similar balance to what I had (which may be a purposefully unbalanced setup). Then I can determine which logical set to change when working on a setup.
