A man with one watch knows the time. A man with two watches is never
sure. Redundancy increases auditability. Remember triple modular
redundancy. It can be overdone, but you really want independent
stored records, so that you can cross check them. And you need a way
to handle it if they don't match. And that way may involve a
decision by an election judge.

Remember, failure to match is a problem that should be reported.
It's a discrepancy to figure out the cause, not sweep under the rug.
