Each of the four systems is rated for each criterion on a ten point scale, according to the importance of the disadvantage which has been observed: 10 indicates a very serious drawback, and 0 the absence of the considered disadvantage, as follows: 0 none, 1 minimal, 2 negligible, 3 small, 4 moderate, 5 medium, 6 considerable, 7 large, 8 very large, 9 enormous, 10 extreme, maximal

The figures noted above can be considered unreliable, since they result from simple evaluations lacking a sufficiently objective basis. It may thus be interesting to see what happens if they are replaced by a binary system, in which 1 means "this disadvantage is present" and 0 "this disadvantage does not exist". If we switch to such a system, which can be deemed to be objective, it is significant that the communication system with the most advantages is still the fourth one, although this calculation method is particularly unfair to it. Indeed, if six months of Esperanto afford a communication level demanding six years for another language, it does not give a fair picture to give all systems which require language learning an equal mark of 1 for this first criterion. But at least this way of reckoning precludes the justified criticism of subjective rating. Furthermore, in order to give all other three systems the best chances, we can remove criterion b (previous government's investment) for the European Union and add it to the fourth column, considering that, if the Esperanto system were adopted, governments might feel called upon to organize teaching of that international language.
