Page Rank Not Related To Links - 2

This is getting to be too much data, so let's make a table.

Site URL	Google Links	Page Rank
www.dmgreer.com	19	5
www.luxefon.com	5	4
www.3dskimaps.com	0	0
www.hillcrestcheer.com	3	4
www.wujidomartialarts.com	15	0
www.taichidallas.com	0	3
www.gomountain.net	1	2
www.dallasmartialarts.net	8	3

There's no rhyme or reason to that. Why does dmgreer have 19 links - PR5, while wujidomartialarts has 15 links - PR0? Why does taichidallas have 0 links - PR3?

Plus, not all of the links are being counted. For example, my dmgreer site has plenty of links to 3dskimaps, so why aren't these counted? Also notice if you look at www.dmgreer.com with the Google Toolbar, the links are all coming from 3dskimaps, hillcrestcheer, and dmgreer. Links from luxefon are not counted.

What's more, if you look up "wujido" in Google, you'll get 2480 results. Since all those results are coming from my own websites, I know that they all have links to www.wujidomartialarts.com. So why are only 15 counted? And why does www.wujidomartialarts.com/catalog/ have a PR2 when the home page has PR0?

Also, I have links from my PR5 site to wujidomartialarts. I think all this clearly shows that links alone do not good Page Rank make.
