How is it misleading? Saying that someone is in the "Top 5%" most viewed profiles is pretty straightforward. Just because there are a lot of people in the top 5% doesn't make it "misleading".
Misleading doesn't necessarily mean lying.
Now I'm wondering what I need to do to market myself there...
People who use LinkedIn actively will get way more views since they will be adding connections and viewing other people's pages more (LinkedIn emails people your contact info if you view their page).
At first, being top 5% made me feel popular. But considering the pool includes users who created an account 3 years ago and haven't touched it since, I'm not so sure.
