1997 Computerization
In 1997 the Election Commission computerized
the City of Cambridge PR elections using a precinct-based optical
scanning system and specially designed software. The PR count, which
used to be performed manually during the course of a week by a staff of
over a hundred, is now completed in a matter of minutes through the
electronic sorting, counting, and transfer of votes. Unofficial results are available on election night. These results are “unofficial” because all ballots have not been counted. The tabulation does not include ballots with write-ins or ballots marked in a way that cannot be read by the scanners. These are auxiliary ballots that must be processed manually and added to the computer totals. They are added on the day after elections. Only there are the results declared to be officials.

Error rate
In Cambridge, the elections have an average of 3,16% error rate. This figure includes both incorrectly marked ballots and blank ballots where the voter may have only participated in a higher-level election. In the future, to further reduce this error rate, Cambridge could allow error correction for the voters.There were very few invalid ballots.
