The geometric mean is a more robust and accurate way to find your If you calculate this geometric mean you get approximately 1.283, so the average rate of return is about 28% (not 30% which is what the arithmetic mean of 10%, 60%, and 20% would give you). Any time you have a number of factors contributing to a product, and you want to find the "average" factor, the answer is the geometric mean.
