Pardon my English!
I have two questions here..

1) How usually does it tak to update my website PR?

my website has PR1, although a PR5 website links to it as for a PR7 does (recently).
my website PR hasnt improved although the two websites that links to it are cached by google and my link is shown there!

2) How come that the PR of the cached page is so different than the original page?

both of the two cached pages that link to my website have PR3, although the original pages has PR5, PR7!

TIA

I haven't been following the who Google thing recently as much as previously.

I too would like to hear from someone that has been following it more than I. I realize that nobody really knows, but I have acquired a lot of good backlinks recently and would love to know when we might expect to see the next PR updates for websites!

I don't use the Google toolbar (on a MAC) and it might just pass me by without it!

I believe that the most recent backlink/PR update was around the 20 - 28th of December, sorry I forgot to write it down this time, so I can't give you exact figures.

In general, it is about ever 5 - 6 weeks, though there have been instances when G seems to skip a cycle.

The 20-28th update was rather anti-climactic for many people as I suspect that PR and algo updates were not radical (enough?).

Should be some movement towards the last week of January, unless Google waits till it gets the PubConf attendee list and factors that into the new rankings. ;)

The last major PR/backlink update was Dec 6. The one in late Dec seemed to be more of a tweak.

There's no predicting how often they'll do it, but yeah, 5 or 6 weeks might be about what you could expect.

I can't wait to see what the PR update brings, there's some "throwaway-new-domain-spam" sites clogging up my terms, slowly, one by one. It's like a spamming cancer in my terms over the past 36 hours or so, all the same guy.

I know his crap won't stand up to further processing and analysis by G, but cripes it's ugly in the meantime.

Let's not get off topic please!

Ok, Google update PR every 4-6 weeks.
Now, how come that the PR of a cached page is different than the PR of the original page?
I noticed that many, if not all, of the cached pages (in any website) have PR3. Any clue?

Why should the PR of the cached page in Google be in anyway related to the actual PR of the real page on the real site?

The only incoming link to the cached page is that from the SERPs. The cache is duplicate content.
