- Personally, I think the "proof" is weak. Worlton has an earlier, less
- frequently cited paper saying the harmonic mean is the way to go. The above
- authors didn't do enough literature checking. If the arithmetic, the geometric,
- and the harmonic mean are all suspect, then don't trust any of them.
