I so don't have time for this right now, but it sounds like a really interesting problem. Not sure I'm eligible to participate (my PhD advisor is apparently one of the judges, which I think explains a conversation that I had with him a couple of weeks ago involving a lot of intentional vagueness on his part), anyway, but I bet that I could do a pretty decent job if I had the time to sink into it. (Especially considering the data that they have but are not using...)

argh.
