Does 'guess' PR count in SERP?

versus 'real' PR.

I know there is a real calculated PR (based on inbound links coming form other sites) and a 'guessed' PR for other pages of a site (which is mostly one PR number lower), if they don't have inbound links coming for other sites.

I have several questions, even after reading many threads on Webmasterworld about links and PR:

Does an internal link from my homepage with the 'real' PR to a sub-directory page on my site pass 85% of this PR to this sub-directory page, assuming it is the only link on the page?

Does this 'guessed' PR of the sub-directory pages count in SERP's as if it was a 'real' calculated PR? Or is a guessed PR = 0 for SERP's?

Does it also counts to distribute PR to linked sites I have put on this sub-directory page, or is a guessed PR = 0 for links pass-through?

I hope it's not too confusing, but I am really curious...

The 'guess' PR is only for URLs that are not in Google and do not appear in the SERPs.

Thanks CIML! If I understand this right: if a page is not cached by Google, it obviously can't be in SERPs, and it's real PR value is 0. So any link on it to another page is worthless in terms of PR?

Is the same true for page that are excluded from caching by TAGs of robot.txt? Regarding the link PR value I mean?

If the noarchive META tag's been used then there may well be PR given from it, so you need to search for the URL in Google to see if it's in the index or not.

If it's banned in /robots.txt then outbound links don't count (because Google shouldn't read the page). You might see the URL in Google by searching for it, but the SERP title will be the URL not the HTML TITLE.
