For my new project i need to know the optinion of the fourm.

On a Point base PR 1 being 1 point, how much power would you give a PR 2,3,4 etc backlink?
i was thinking about PR n^2
so
PR 1 = 1
PR 2 = 4
PR 3 = 9
PR 4 = 16
PR 5 = 25
PR 6 = 36
PR 7 = 49
PR 8 = 64
PR 9 = 81
PR 10 = 100
But that is propably not enough...
What kind of equation would you suggest?
Any idea is welcome...
 
The PR 10 propably wont be too important for my project
its more about the PR <=6 that will come to use often...
 
If we were saying a PR1 is just a plain blog spammed comment, and the PR10 is a link you paid for on a site, I would say over 100k, but its not like you would ever get one. I got websites with 50k+ indexed links and I'm sure a PR10 would increase the SERPs over double.
 
Last day i found a PR chart, look at this :

But i believe it's not accurate.
 
You need an eigen vector equation, that will do the trick.

Its not power 2 based, nor its logscale based. Its linear, and rescaled from eigen vector.
 
Moreover, a link from PR6 page that has a lot of internal/external links is by far less powerful than link from PR5 page with no internal/external links.
