Remember, we are looking at the probability that a result is indeed precise, not the impact or effect of that result in any further context. For the specific case of Web accessibility, the relative priority level of the checkpoint (or success criteria) indicates that impact for people with disabilities. This is different from the earl:confidence value we are talking about here.
