Actually, that infographic shows the vast importance of reducing load on the engine. Reducing that 11% aero loss to even 10% has a multiplying effect as we trace back the power usage to the energy source. 1% reduction in engine load will mean that the 69% 'engine loss' use gets reduced to 67%. So, for a 1% engine load reduction, you get a 'free' 2% reduction from 'engine loss' for a total of ~3% less fuel used.
