For example, in a motor vehicle the power-to-weight ratio is important as it affects engine performance and fuel economy. In other words, for a given engine size the lower the weight of the car and the better the fuel consumption. The more weight you add the lower the performance. Your car has a heater which you only use when it's coldEverybody knows that carrying around code which is either rarely used or not used at all is an overheadeverybody knows that claims without measure the impact are worthless
