Out of curiosity, are those what could be considered "reciprocal" links
No. I rarely allow any outbound links unless I think very highly of a product or service. These are not reciprocal links.
I don't know if you can expect your "entire site" to get a boost
As a seasoned programmer by trade, I understand the mathematics behind PageRank very well. I don't expect a domain or entire site to get a boost just because it has a few nice backlinks to inner pages. What you call 'sculpting' is exactly what I'm talking about. Said page links to a few other sections of the site and they get a boost, what they link to gets a boost, you get the idea.
What I'm wondering about is how long it takes Google to refresh that linkgraph and implement them in to the rankings. The effects right now of links seems inconsistent with the exception that public pagerank values have increased but overall SERP rankings have not.
