Re: Hand Recounts of votes recorded on DREs
Arthur,
A testing of the DREs used in an election should allow you to evaluate
the system within statistical limits. Simulating the election should
give you the information you want; you can compare known inputs to
observed outputs. Since this is post election, it does not satisfy the
same requirements as would AVVPAT. An automated test system should fill
the bill very well, however, of estimating the performance of a given
voting system.
This is my personal and professional opinion, and it does not
necessarily reflect the opinions of my employer.
Cheers!
