To add to the theory:

Our site does the same thing. Level 1/2/3 get the bulk of the indexing. Level 4 where the BULK of our content lies is a small percentage. Pretty much google is indexing the "directory" navigation of the site not the content. I can get any page to get indexed simply by adding a link to the home page. As soon as the links gets taken off the page disappears. I find it highly unlikely to fit 2000 or so links on the home page. So the site is built for the visitors and split up into a feasible directory structure.

What I am finding hard to understand the bulk of our incoming links are to the deep content. Not many links to individual pages but the sum of which is a ton. If those pages are not being index/crawled then how is PR fairly calculated? What I mean is internal PR from those pages adding to the circulating PR as well as incoming links also adding to the PR circulation? Any thoughts on that matter?
