Default Spring and damper combination

Everyone,

I need some help in term of understanding and setting up spring and damper combination. I noticed that many rc car racers tend to match soft spring with light damper oil. Their theory is simple, with light damper oil, it will be easier and quicker for the shocker to move up and down to absorb the bump.

I have read somewhere in a motorsports magazine (1:1 scale) about the suspension setup. The suspension tuner increases the damping rate everytime he uses softer springs. On the other hand, he reduces the damping rate as he uses stiffer spring.

His theory is simple, if the track is bumpy, softer spring is a way to go. However, soft spring tends to cause the vehicle to move up and down. With more damping rate, the oil will be able to absorb the vibration and energy for both compression and rebound (both ways). This way, the vehicle will not move up and down during and after going over the bumpy section.

Anyhow, I need your expert opinions on which one is correct.
