"There is no consistent difference between the ones in and out in terms of PR"

You cannot see the PageRank of individual urls. TBPR 4 is on the low side anyway, so its not surprising to see fluctuations.

There is no correlation between TBPR and % supplemental. If you owned a TBPR 5 with 10 pages, you'll always have 100% of your site in the main index.

As for Google basing indexing on PageRank, it's a flawed concept but I don't think they have a better alternative, since Googlebot doesn't understand what's written on a page.
