Unfortunately the top 2006 final rankings aren't readable (at least from my browser). And there were some distributions missing, so that year's rankings were partially incomplete, despite a herculean effort by Susan.  After some research, I concluded that the top places went to:

2006: Wheaton, MLDeerslayer, Paulob?... 118 contestants

2005: SageNolos, MLDeerslayer, dougmoore, kevindow, FredP... 100 contestants

2004: AKHalea, monkfish22, pointyhairedbos... 40 contestants

2003: dcapbtls, kevindow, danasu ...33 contestants

It might be worth noting, that the current leaders are also prominent in prior contests. But MLDeerslayer's all gold portfolio (same picks ea yr) took dead last in both 2003 & 2004!  Hopefully that won't the case in 2008 for some of the very aggressive (risky) portfolios  ;-)
