Very nice find!

And a good point. It is important to note the engine RPM changes. When they occur, it affects how the fuel is burning in the engine. Variable and constant RPM's are two completely different processes happening inside the cylinder. In other words - when on constant RPM (provided we have the ideal mixture) the engine is burning fuel just like it should have, while with variable (changing) RPM the mixture and overall fuel burning process is far from ideal.

i. e. - for the very same reason there are two different fuel consumption figures in cars: one for driving in a city where throttle changes are frequent and fuel consumption is higher, and another for highway driving where fuel consumption is much lower.
