I am curious who stated that. By the way, it depends also on the type of track you run.

In general: With a taller gearing your engine has to work harder to reach max rpm. With a smaller gearing the engine will reach max rpm sooner.
The speed of reaching max rpm is depending upon finger speed If both movements are exactly the same, the consumption of a taller gearing will be less. And ... you dont need to open the throttle as wide to reach the same speed
