I can believe that chart to be accurate for the VW 130Bhp engine. We too have a Skoda Vrs and I can feel the engine become more torquey and efficient in the range of 1,500-2,500 rpm. This is borne out by the instantanoius mpg reading climbing rapidly once 1,500 rpm is breached.
A standard rule of thumb used to be drive within the range of peak torque +1000rpm -500rpm for best efficiency. Under light load lower revs can be used without the engine bogging down. I'd be wary of running high loads at low revs in a diesel as that can create very high forces on the big ends and crank.
For hills I use the 'arrive a bit quicker and let speed bleed off slowly' technique.
In the Vrs one needs to be careful to not be in too high a gear under load, it seems to increase consumption.
