I have been pondering on this topic for a while and here is what I have came up with.
One of the best ways to optimally sub-optimize the efficiency of a resource is to fuelling them in a suboptimal way.
Suppose there is a driver who is an expert F1 racer. So we can infer that :-
1. Driver is a skilled Drive.
2. The driver is used to of F1 Cars.
Now, if you will hire that driver for races, then obviously he will be a good bet since the driver is trained to do so, is expert in the domain and usage of the tool driver uses ( F1 car in this case ).
