Story in my high-school calculus class 30 something years ago was that there was a time when banks were competing on compounding. I do remember some advertizing as compounding daily. In that climate, one bank decided to offer compounding continuously. (Maybe after another offered compounding minutely or secondly.) The difference gets ever smaller very fast, though. Maybe about the same time, there was competition between blender companies on how many speeds they had. Six, eight, or more. Then one company put a knob on for an infinite number of speeds, but no-one would buy them. Maybe the same thing happened to banks and interest. -- glen
