Do you have an aggregate average for all matches? (a histogram showing the distribution would be really cool as well) It would be interesting to compare against the predictions from
this thread.
Also, I agree very much with the point about balancing. Despite the fact that most teams could not score enough points to make up for a balance, balancing seemed to be a complete afterthought in most of the matches that I watched (the matches involving 148 in the elims being a spectacular exception).
