Its very influenced by the crawl rate of the linking site
A good point. In my examples above, some of the links aren't even in the Google cache yet, but some very important ones are. As I mentioned above, PageRank values have really gone up a notch across the board since the last update.
My experience is that if I don't see a bump within a fortnight, its not going to happen.
Please clarify. I know that text links with relevant anchors can provide a boost in a short period of time; this is both one of advantages of Google and also an ultimate failure in their algorithm. What I'm more interested to know is how long it takes Google to update the site-wide part of their algorithm.
The actual pages that have new links *have* seen some increase in traffic to a small degree over the past few months, but I haven't seen any site wide improvements except for PR values increasing handsomely.
