Economic optimum tension
Engineering is limited in the quality of the answers it can give, even on engineering variables, such as tension settings as we illustrate in this clip.
While engineering might get you to good, or even good enough, only economics will allow you to get to best. Here we use the word best synonymously with optimum. The reason is that tension, or any other engineering variable, is both good AND bad, at the same time. In layperson’s terms, you are charged with finding the best place “between a rock and a hard spot.” Only economics can help you find that best place, the economic optimum tension, the one that maximizes profit. See how.
