Harmonic mean rate utility
WebThe harmonic mean is the reciprocal of the average of the reciprocals of numbers. So the harmonic mean of a, b, and c is 3/ (1/a+1/b+1/c). It is used sparingly, but is well studied (e.g., the AM-GM-HM inequality). Just like how the arithmetic mean can be heavily swayed by large elements, the harmonic mean can be heavily swayed by small elements.
