Here's a graph showing how the probability of winning the Argentinean soccer championship changed over time for each team (time goes from left to right, and probability goes from 0 at the bottom to 1 at the top). Click on the graph to enlarge:

Hindsight being 20/20, it's easy to read too much into this, but it's interesting to note that some qualitative features of how journalism narrated the tournament over time are clearly reflected in these graphs: Velez' stable progression, Newell's likelihood peak mid-tournament, LanĂºs quite drastic drop near the end, and Boca's relatively strong beginning and disappointing follow-through.

As an aside, I'm still sure that the model I'm using handles low-probability events wrong; e.g., Boca still had mathematical chances almost until the end of the tournament. That's something I'll have to look into when I have some time.
