Not convinced by that article at all. Basically because I am not convinced that the level of advantage seen by RB can be explained by a slightly better blown diffuser.
The article states they maintain 95-100% of the exhaust gas whilst off throttle. That seems a monstrously high figure, implying that the engine is still running (almost) flat out even when the throttle is released - I cannot see how they get that volume of gas out without some big bangs going on.
The difference between the oppositions 70-80% to RB's 95-100 is also not that great. It may be 15-20%, but that is on a aero device that only supplies some of the downforce on the car - I dont have an exact figures, but lets say 10%. So 20% of 10% is 0.5% overall. Now, that's not available throughout the whole lap - only when off throttle. Say 25% of the lap, so we now have a 0.5% advantage for only 25% of the lap, so overall, 0.125% overall advantage.
The RB shows more than that in qualifying.
Something else is going on.
