The ADAC testing puts all tyres through the same tests.
The lowest RR there, actually means the lowest RR amongst the tyres being tested.
The EcoContact 5 is rated with a "B" for fuel efficiency in the new EU labeling system - AFAIK no A label (best) tyres are yet commercially available (though a few manufacturers have boasted with them).
Between A (best) and G (worst), there's apparently about 10% difference in fuel efficiency.
