The point I was trying to make is that if the ultimate goal is to accelerate from 30-40MPH and at full throttle that would take 15 second in 6th gear at 2000-2300RPM, but at half throttle that would take 4 seconds in 3rd gear at 4000-4500RPM, less fuel would be used in the latter.

The above numbers are arbitrary, I didn't look up SER acceleration rates or gear ratios to determine exact figures.

I'm not trying to argue either, just getting facts straight. Anyway, actually, what I said is always the case. BSFC charts show that higher loads always provide more horsepower per amount of fuel used. Therefore, running at lower loads will always be less efficient. If he used full throttle at 2000-2300 vs full throttle at 4000-4500 it is somewhat arguable which is more efficient because we don't have a specific BSFC chart for the engine. However, running an engine (near) full throttle will always be more efficient than half throttle.
