Indeed, the natural district threshold cannot be automatically projected to the national level and directly compared with, say, the nationwide legal threshold. Some have tried to devise a formula and calculate the nationwide natural thresholds (see the tables at the end of this subsection). However, such calculations cannot be fully precise; any such calculation would remain approximation because, among others, the real force with which the thresholds curtail access depends heavily upon particular distribution of party support, the number of districts, and the number of legislators returned within each district. These characteristics may vary significantly, and some average reflection on the national level (or to some extent even the average district level) might not fully capture the exclusionary force already at work within some specific districts. Moreover, even if sufficiently approximate, the nationwide natural threshold is a concept that does not have all the properties of the legal threshold while it has some unique properties of its own. Furthermore, “whereas natural thresholds tend to widen the proportionality gap between the share of votes and seats, favouring especially the biggest party, legal thresholds foster a more proportional distribution of seats among those parties that passed the threshold”. Hence, the two thresholds, when translated to the national level, could not be directly compared as if they were one and the same thing.
