Re: Research on frequency and severity of failures

>I'm guessing when you say an issue, you are not talking about the number 
of instances of that (type of) issue but just the issue itself, such as 
"Missing heading tags for visual headings" being one issue, for which 
there may be 100's of instances.

For clarity, I'm interested in both -- quantitative information on number 
of occurrences for any single Success Criterion (how many instances) as 
well as relative frequency of occurrences across all the WCAG Success 
Criteria (how many criteria failed).

When I was working on a model for accelerating accessibility, I had very 
similar questions not only about the relevance of WCAG levels, but the 
nature, frequency, severity and remediation efforts for accessibility 
issues. I've identified this as a research opportunity, as I did not find 
much useful data. I'd welcome any references, data sources or 
non-anecdotal findings on this topic.
