How many PR5 make a PR6?

is it mathematical?

how many incoming links from PR5 sites would help boost my site from a PR5 to a PR 6? Does anyone else find it difficult finding sites that are PR7 or 8 to request links from?

I have the notion that its nothing more than a simple log scale, so if it log 6.2 you need 6 or 7 PR6 sites to link to you. But I have no proof its linear.

Too many other factors at play to offer a definitive answer.

You also need to consider...

Is it a "high" PR5 or a "low" PR5? (PR resolution on the toolbar doesn't reflect the "true" PR of any given page)

How many other outbound links are there on the PR5 page? (The PR that is passed on is divided by the number of links on the page)

Are the links from different domains? (differing opinions on this point)

Is the link format indexed? (e.g. javascript)

Is the link going to be spidered by Googlebot? (It may not be if it's buried below the 101k point on a large page)

As mentioned before, the answer depends on several parameters.
However, an rough estimate would be 10*(average number of outgoing links on the PR5 sites).

I'll be really general here - this won't apply to everyone, but's it's generally not too far off the mark

PR6 - 50
PR7 - 1000

From this thread...

what does it take?
pr3 to pr4?
[webmasterworld.com...]

...two posts by ciml, with my comment in brackets:

To get PR4 [from PR3] you need about "n" links from PR4 pages, or about "n x n" links from PR3 pages, or about 1 link from a PR5 page. I say about, because the number of links on the linking page make a difference, as does whether the linking page is a at the top or bottom of it's position in the Toolbar.
People disagree over whether "n" is about 6 or 10.

And, in answer to a question abt 3 PR6 links...

I'd expect roughly PR5 from three links from PR6 pages.

If the same rules apply going from PR5 to PR6, this suggests "n x n" PR5 links, or somewhere between 36 and 100... consistent with what Pegasus says.
