After not winning in a BUNCH of other years. 2007, Curie. 2005, Archimedes, IIRC (might be another, but not Newton). I want to say it was Galileo in 2004--Archimedes won. I don't remember the stacked division in 2006, but it might have been Newton with the 254/968 twins. (I don't remember which division won.)

2004, 2005, 2007, 2010, stacked didn't win.
2008, 2009, 2011, stacked won.
2006 needs more research.

I think that's a bit more odds against the stacked division winning than 25%...
