Click fraud only 2-5%?

Google Adwords Teamannounced the launch of a new AdWords feature enabling advertisers to have a much more detailed picture of invalid click activity in their account

These clicks are filtered in real-time by their detection system. The metrics of “invalid clicks” and “invalid clicks rate” will show virtually all the invalid clicks affecting an account. The resulting data will of course differ from one advertiser to the next. In addition, a much smaller number of invalid clicks may also be credited to advertisers’ accounts after-the-fact, as the result of a publisher being terminated from the AdSense program for invalid click activity. These will appear as account-level credits.

The click fraud report only works on the campaign level. First users reported click fraud between 2-5%. I ran a report myself and my US accounts have an average invalid click rate of 3.35%.

The invalid clicks report is a smart move by Google. The integration is limited to the reports, which means that Webanalytic Gurus and professional SEO's won't be able to explore this more. I am wondering how webanalytics vendors, webmasters and interactive agencies react to the unexpected low invalid click rate of 2-5%.
