I agree completely tedster. In fact my blog directory is TBPR 4 while my root TBPR is 3. When I say a TBPR 2 site I'm using that as a short hand for a site with a total IBL "power" (all inbound PageRanks to a domain added together) that's pretty weak. Googlers often resort to the same shorthand in their Webmaster Guidelines by attributing PageRank to a site, rather than to a url, though technically they're also making a mistake.

The way PageRank flows through a site is unique for every site; How PageRanks flow into a site is also unique for every site (A blog might have multiple entry points, as people link to different posts, while a commercial site with thin product pages might only have one entry point - the home page). There is still a tendency for PageRank to gravitate upwards (e.g. PageRank will gravitate toward blog category/archive pages, as they're often linked to from every page, though again, it depends on your blog setup).
