Your profile page with PR3 is excellent as HP is a PR5. Google ranks each page based on their own criteria. I am not sure what all the criterion are. But I know that they crawl the profile page too and the content you have there has to be relevant to the rest of your pages.
Google ranks pages from 0 - 10 with 10 begin the best and 0 being the worst. Your page will start ot with a n/a and as soon as you get into rank you will see numbers. With relevant high rank links, keywords and traffic you may rank higher as time goes by.
