My experience with "What happens when PageRank rises/falls" does not mirror what you said and I've been doing this for 4-5 years at a "basic" level. When a PR change occurs on our site, we definitely see traffic shifts both in terms of the number of visitors and in the quality of traffic. No question. The most recent one I remember having a big impact on us was May, 2010. We had about 3 pages go from a 4 to a 0 (still don't know why) and almost immediately our traffic numbers + quality for those pages was #$&%. Note that the change in traffic was right at/around the time of the PR change - not a month before, two months before, or even a week before.
