I had an almost identical example for a new site. I linked from every page on my hub site and I got a PageRank of 4 for the new site. There were about 350 inbound links. The following update I had incoming links from 10 additional domains--up to PageRank 5.
But look at the overall concept. Google ranks sites highly because they are hubs. You can't be a hub with only one spoke. Potentially, if Webmasterworld had several PR7 "hub type" pages, bestBBS might have benefited enough to get a higher PageRank.
