If official election results processed by an electronic tabulation system, at which level results are entered into an electronic tabulation system?

NEC official's response: Depending on the type of elections (e.g. presidential elections, parliamentary elections, local elections) and voting method (e.g. early voting, election day voting, home voting), the counting unit varies by voting district, Eup·Myeon·Dong (town-, township-, neighborhood-level administrative entities),
election, and constituency. At the counting center established by each Gu·Si·Gun (district-, city-, county-level municipalities) election commission, the results of each counting unit are entered into the tabulation system.
