Three systems do not fit neatly under any one of the above-mentioned categories. The Single Non-Transferable Vote is a multi-member-district, candidate-centred system in which voters have one vote. Limited Vote is very much like SNTV but gives voters more than one vote (however, unlike Block Vote, not as many as there are seats to be filled). Borda Count is a preferential system in single- or multi-member districts.

These systems tend to translate votes cast into seats in a way that falls somewhere between the proportionality of PR systems and the results of plurality/majority systems.
