Perhaps more generally: The effectiveness of energy put into an action can easily be a non-linear function. Most gain in value may be achieved at a certain energy level, such that energy differences significantly below or above that level hardly change anything.
In some cases the function may even be non-monotonic, where spending some larger amount of energy is actually worse than spending some smaller amount.
