What percentage of total backlinks are shown by "Open site explorer" tool?

[RyanSat]

What percentage of total good quality back links are shown  in the "Open site" or other toolbar. I was checking backlinks for a spammy sites which ranks in #3-5 for a competitive keyword.But could not find nothing more than 10-15 PR4-5 in content backlinks and rest are just forum/profile signatures.

24% Trust/Authority of the Host Domain
22% Link Popularity of the Specific Page
20% Anchor Text of External Links
15% On-Page Keyword Usage
7% Traffic and Click-Through Data
6% Social Graph Metrics
5% Registration and Hosting DataI

For one of my sites comparing to google webmaster tools on a page that has been established for over a year webmaster tools lists 30000 links and opensite explorer lists about 3333 links so about 11% though i doubt it will be 11% for all sites as there could be many factors involved in this effect.

number of linking domains is about 90% of what it says in webmaster tools.

hope this helps
