“The NEC later released a dual-entry results management system, based on an Excel spreadsheet, to be used concurrently with a more sophisticated software results management system designed with electronic safeguards to prevent fraud and human error. Used together, the two systems had adequate safeguards in place to isolate questionable results. The results management system included 11 quarantine factors that flagged polling stations with potential anomalies for closer scrutiny. Polling station results that were put into quarantine included those where the number of participating voters was greater than 95 percent of the number of registered voters, the number of ballots issued to voters was higher than the number of registered voters or participating voters, and the total number of votes in the ballot box was higher than the number of registered voters.”
