Agree. I think this is a manufacturers graph that's used as input for the airframe manufacturer to eventually come up with the speed/power/map/rpm/fuel consumption figures that go in to the POH. A graph like this would be virtually useless for the pilot.
The other thing to note is that the "ECO" lines are most likely "leaned for best economy" while the "Power" lines are most likely "leaned for best power".
What engine is this by the way? It's not your typical Lycosaurus, which has a maximum RPM in the 2700 range. Must be something geared. Rotax 912Si or 912ULSi?
