As its name indicates,consecutively halved positional voting (CHPV) is a type of positional voting system in which weightings are applied such that the lower of any two adjacent rank positions is worth half that of the higher one.^[1] In single-winner contests, voters cast their preferences using a ranked ballot and the option gaining the most points overall wins.

In multiple-winner elections, CHPV is a highest averages party-list system in which the descending weights associated with the candidate rank positions on the party’s list are consecutively halved. Elections to the Legislative Assembly in Macau employ such weightings.
