The time taken by testers to complete tasks on the 30 top compliant sites was analysed to see if there were sites that were overall faster than others, and to break down any variance by impairment types.

For each tester impairment type, the fastest ten sites and slowest ten sites were selected. The average task time for each site was used to determine the fastest (those with lowest average task time) and the slowest (those with highest average task time).

With only a couple of exceptions, sites that were in the top ten fastest for some impairments also appeared in the slowest top ten for other impairments. This was a surprising result. It was expected that there would be some variation and that sites that were fast for some impairments would be average for others. However, it appears that there is a marked variance, and one could almost conclude that if a site is going to be fast for an impairment type then it will be slow for another.

The key conclusion is that designers need to take a much broader range of issues into account and use a wider range of testing to minimise barriers to using websites.

Table 4 lists the ten fastest sites by tester impairment type.

Table 5 lists the ten slowest sites by tester impairment type

Table 6 list the ten fastest and slowest sites by tester impairment type.

The key point in the tables is that almost all sites that are fast to complete tasks by one or more impairment types are also one of the slowest to complete tasks by one or more of the other impairment types.

No site appeared in the list of ten fastest sites for every impairment type (three impairment types were the maximum recorded for any site).
