For me it's less a trust thing and more of an "it's useless without more data" thing..
That is, supposed it's skewed from a targetted optin mailer from a partner sponsor sent to 3 million people with a conversion rate of 1:200? How does that help me if I'm using PPC and sending a few hundred hits a day? lol
Opposite could be true as well, such as 10 partner sponsors sending to 1 site from consoles and slaughtering the overall ratio which might otherwise be pretty good.
You get my point..
