Accuracy and repeatability in optical ballot scanners.

Hello All:

I have been reading some articles about problems with
Optical Ballot scanners. I believe this this was in
Boulder, Colorado. It seems there was a problem in
general accuracy of reading ballot markings and in
repeatability of reading ballots through multiple
times. I know that Doug Jones has written a bit about
optical scanners but I was wondering if other people
had heard similar things. More specifically, I was
wondering about measured error rates and
repeatability.

I'm thinking that whatever the error rate is
discovered for optical ballot scanners that these be
used as the threshold numbers for setting accuracy
standards for voting equipment and for recounts. I
know that there was a discussion on this a month or
two ago but I think that there was always the problem
of how to set a numerical base level of error
tolerance. Seeing as optical scan equipment seems to
be the best pragmatic standard hardware I could see
this as a good point to nail down error tolerance.

Does anybody have any comments or ideas about this?

Thanks, Ed Kennedy
