How valued are .edu links? Here is one amazing fact!

Hi

I have beed doing reasearch and research about .edu links.
Finally found 1 free .edu link--


But after checking some sites with lots of .edu links--albeit without PR value and checking their Page Strength with SEOMOZ--I am little bit puzzled:confused:

This site has 217 .edu links--PR5 and still PS4.5:(

http://www.seomoz.org/page-strength/www.tipcell.com

So is it just a might or .edu links greatly enhances PS?

Please post your comments!

Yes--that is the puzzle.
I can see many of us are trying hard to get a good .edu links. The other day one friend bought a .edu PR6/5 link for $90/m.
I am just wondering if they help really differentiate from other links based on PR & PS influences.

Any of you know how often do seomoz guys update the tool?
