The Schwalbe test did it on grass, packed dirt and loose dirt I think.
If you aren't on a road, lower is better.

No way . the less tire touching the ground (more pressure) the less rolling resistance you'll get. Less pressure is better for absorbing bumps but if you have any sort of rear suspension then this would negate the need to have lower psi in rear tires. Basically, the article is saying low pressure tires act as a suspension system that allows a hardtail to maintain controle sacrificing speed.
