F. After the electronic tabulation of early ballots and at one or more times selected by the chairman of the political parties entitled to continued representation on the ballot or the chairman's designee, the chairmen or the chairmen's designees shall randomly select one or more batches of early ballots that have been tabulated to include at least one batch from each machine used for tabulating early ballots and those ballots shall be securely sequestered by the county recorder or officer in charge of elections along with their unofficial tally reports for a postelection manual audit. The chairmen or the chairmen's designees shall randomly select from those sequestered early ballots a number equal to one percent of the total number of early ballots cast or five thousand early ballots, whichever is less. From those randomly selected early ballots, the county officer in charge of elections shall conduct a manual audit of the same races that are being hand counted pursuant to subsection B of this section. If the manual audit of the early ballots results in a difference in any race that is equal to or greater than the designated margin when compared to the electronically tabulated results for those same early ballots, the manual audit shall be repeated for those same early ballots. If the second manual audit results in a difference in that race that is equal to or greater than the designated margin when compared to the electronically tabulated results for those same early ballots, the manual audit shall be expanded only for that race to a number of additional early ballots equal to one percent of the total early ballots cast or an additional five thousand ballots, whichever is less, to be randomly selected from the batch or batches of sequestered early ballots. If the expanded early ballot manual audit results in a difference for that race that is equal to or greater than the designated margin when compared to any of the earlier manual counts for that race, the manual counts shall be repeated for that race until a manual count results in a difference in that race that is less than the designated margin. If at any point in the manual audit of early ballots the difference between any manual count of early ballots is less than the designated margin when compared to the electronic tabulation of those ballots, the electronic tabulation shall be included in the canvass and no further manual audit of the early ballots shall be conducted.
