I agree 30 pages isn't that long for a research paper, and I'm sure Jay had plenty of tables and charts since it is a statistics paper. The key is to have a really detailed outline. My outline for my research paper was about 3 pages long, double spaced. Most of the lines were only a few words, but there were a lot of scribbles on the page. That outline got me to about 25+ pages.
Just for kicks, I've attached my work.
