For example, how many other outbound links the PR4 pages have.
So I dont think anyone could give you an exact numerical value, although I think there was a chart a few months back showing the approx. number of inbound links that different PR sites had.
Perhaps someone else has a link to the thread?

Might even depend on if the links are all coming from 1 site or different sites.
Well, usually it will be like 40 or so.
i'd agree that there is no straightforward answer,
one way of finding out and discovering a whole lot else is to find a pr6 page on google
run a search for
link:urlofpr6pageyoufound
this will show all the pages of pr3/4 and above that link to it, you could then check the pr of each of those pages and see what the answer is.

If you can be bothered - that could be a lot of links to look at?
Or is it really around the 40 mark?
Most of the PR6 sites I glance at usually just have one decent PR7 link and that usually does the trick on it's own.

i agree, i actually think it is a lot more than 40, i think it is very hard to get a pr6 with just 3's and 4's incoming.

That's what I was thinking - I would imagine it takes around 40 x PR5 links to make a PR6.....
srinivas - PR really does not seem to affect the current SERPS in the way it used to, so I wouldn't worry about it too much. Go for targetted inbound links that gain traffic.

One of my sites has just bumped up to PR6 after being PR5 during the 6-8 week strangeness of Google (had just hit PR6 from PR5 the month before the strangeness, then went down to PR5).
We have a way lot more than 40 PR4 links - quite a few PR6 and PR7 links as well.
I would assume because we recently hit PR6 that we are a low PR6, so I would say that it either takes a lot more PR4's to make a PR6 or higher PR's (5 and 6 in this case) arent noticably different from PR4.
Just my observation for a single site and not necessarily the rule for PR allocation.

We only have about 100 links on our site. They are very qualified links IMHO and the only thing we've added is more content.
Sorry no answer here:(
link:www.myside.combecause the PR of those pages is too low for being added to the SERP (e.g. a PR1), will still help to increase your PageRank.
I saw a site that has 13 inbound links from 5 different sites....and their PR is 6...how is this possible?
One of those 5 sites is probably a PR7.
1. PR's are exponential. My guess is about 6-7 of a given PR adds up to the next PR i.e. PR+1. Let's assume this multiplicative factor to be 6 in PR5-PR7 range.
2. Link from a PR X page is misleading because as people have pointed out here, it depends upon number of links from that page. Say a PR 6 page has 36 outward link. It means each link will be worth about PR 4 (since 6 * PR4 = PR5; 6 * PR5 = PR6; 6*6=36)
3. There is a damping factor of about 0.85 in the original paper. Assuming that only 36*.85 = 30 links from PR6 page will pass out PR4.
4. Since PR values are rounded, there is a vast differnece in two PR6 or two PR7 pages. Some nice estimates can be made, especially in the directory structures, about where in that range they fall.
5. Also look at PR value of pages already linked from that page. Say there are about 100 pages linked out. Look at each of those 100 pages, plot out their PR values, throw out a few very low ones (penalty!) and then the lowest among the rest will give you an idea about the PR that will be transferred to your page.
It will take a few cycles for the PR to be completely transferred.
Also there are some other factors involved too, as others have pointed out. Lots of PR3-PR4 sites are not going to help that much in getting PR6. A few PR6 pages (I don't think PR7 is a must) with few outward links should do the job.
I used multiplicative factor of 6 in PR4-PR6 range as a guess. Some experts think PR value is a reflection of some sort of percentile system.

Taking real values, a rough estimate would be
100 * <average number of outgoing links on the PR4 pages>
i.e. thousands of links from PR4 pages.

PR isn't rounded. Of course, the ToolbarPR value is rounded, but not the real PR value which is taken for the PR calculation.
It will take a few cycles for the PR to be completely transferred.
It can take some time until Google includes all backlinks in the calculation. However, transferring PR from backlinks which are included in the calculation should done in one update. A problem could only arise for sub pages if you have a very large web sites with a hierarchical structure. But even this shouldn't be a problem in practice. (The main problem in this case might be that Google doesn't spider the complete site in one step.)
I have a PR6 site and I am sure that it has no incoming link from a PR7 site, so the PR6 must be generated by the other links. Searching for link:thesite.com shows 109 backlinks. There are some PR6, PR5, less PR4. I don't know how many PR3 and lower there are but can't be that much.
So in my case it took "only" 109 links from PR4 and above to receive a PR6 without a link from a PR7.
