The figures indicate that around 95.5% of page accesses are made using browsers supported by the AIS site
Lies, damn lies and statistics.
Having tried a non-compatible browser once or twice, I think it's logical to assume that a user would not try it again. On the other hand, having tried a compatible browser once, a user is far more likely to return many times, thus pushing this number up.
Far more useful would be the percentage of IP addresses which have only ever attempted to access the site using a compatible browser.
