Jesse - 

  We've provided this information already; you did you review the referenced fee presentation?

 Per page 13 of the above presentation, here are the 2011 actual
 costs as broken down by the existing fee categories:

    X–Small        $1,245,000   11.51%
    Small          $4,506,000   41.65%
    Medium         $2,835,000   26.21%
    Large          $  909,000    8.40%
    X–Large        $1,323,000   12.23%

 We have not done the above calculation, but it can be derived from the
 whois data if you desire to do so.

 That is not surprising at all, and I will note that under IPv6, this effect is 
 even more pronounced (a single ISP with a /20 of IPv6 space will likely exceed 
 the total IPv6 holdings of thousands of ISP's with smaller address holdings.)
