The preferred turnout rates are those calculated with the voting-eligible population as the denominator. The voting-eligible population (VEP) represents an estimate of persons eligible to vote regardless of voter registration status in an election and is constructed by modifying the voting-age population (VAP), by components reported in the right-most columns (scroll right in the spreadsheet).
