Web page accesses do not follow Pareto's Law?

I have a Web site with more than 100 static pages
(http://www.zak.co.il/deaf-info/old/ for the curious).
Recently I had to modify the most frequently accessed pages of the Web
site, according to access statistics accumulated by the Web hosting
service.

What I found was that Pareto's Law does not seem to be followed.  The
top 20% pages account for 57% of the Web page hits, and to account for
80% of the Web page hits, you need the top 40%.  Thus, the distribution
of hits in my Web site is more egalitarian than Pareto's Law (which says
that the top 20% account for 80% of whatever they do) would suggest.

Is this a general phenomenon for Web sites?
Could this be due to caching, proxying, mirroring in remote locations?
Is there a theory for this, which is supported by experiments?
