Hm, and where is this 15% coming from?  Just another assumption?

Note that we asked (per e-mail) the top 500 download sites, and most of 
them prefer to wait and see what Link Fingerprinting is and can do for 
them, because so far nobody really believes that it will do any good for 
them, but that it will add extra work, errors and costs them probably an 
unexpected amount of (extra) money.
