I put up a one page site on June 5th and it is showing a TPR of 3 today. I gave it 2 links from my main site, one from a PR4 page and one from a PR3 page. I'm starting to get reciprocal link requests on this site, so far I'm ignoring those requests. The site doesn't rank in the top 100 for the primary kws yet, but I would not expect it to at this point. This site is on a new domain name (never registered before as far as I could tell).
A second one page site I put up a couple days later (and added no links to it) is still unrated, which is what I'd expect. I think I'll try adding just one link to that sit and see what happens. This site is also on a new domain name (never registered before as far as I could tell).
