Question

"The efficiency of a translation can be judged in terms of the maximal reception for the minimum effort of decoding. In a sense, efficiency is closely related to Joos's "first law of semantics" (Joos, 1953), which may be stated simply: "That meaning is best which adds least to the total meaning of the context." In other words, the maximizing of redundancy reduces the work of decoding. At the same time, redundancy should not be so increased that the noise factor of boredom cuts down efficiency."
Can anybody explain what this paragraph means?((( I don"t really understand...
