RE: Another comment about confidence value.

Sorry, my answer below was a bit short, that was no intentional as I
decided to answer the email as I was rushing to a short meeting. I
appreciate the magnitude of the testing you do. What I'm trying to say,
is that an independent validator who provides a branded stamp of
approval should not automate the majority of their testing - not in the
UK anyway where it appears to be more open to litigation than most
countries. My comment was not directed at you Nils :)

We are doing quite different measurements. We will be trying to do
automatic assessments of a large number of sites (several thousand)
regularly. We will need to do some manual testing, and will base our
tests largely on automatic assessments. In our case we need to base
ourself on probability theory and best practices in statistics to reach
numbers that approximate the perceived accessibility over a large number
of assessments, to make it feasible.
[PW] This will not be accurate and I would question the process itself
of using automation for the majority of your validation.
