The three tables above just give a different weight to each of the programs, explaining the inconsistent results of the arithmetic and harmonic means (the first table gives equal weight to both programs, the second gives a weight of 1/1000 to the second program, and the third gives a weight of 1/100 to the second program and 1/10 to the first one).
上面的三個表只是給每個程式帶來了不同的權重，解釋了算術和調和方法的不一致結果 (第一個表給兩個程式帶來同等的權重，第二個程式的權重為 1/1000, 而第三個專案的權重為 1/100，第二個程式1/10 到第一個。
