OPR is from column O of the Worldrank tab which is the same thing that comes up in the query search.
We often take the average of average and max when we are doing rankings, we call this third quartile (which I think is not strictly accurate) and we feel that it does a good job of predicting future results.
Feel free to PM me if you want the spreadsheet that I used to do the calcs.

The world OPR takes into account all events from week 1 to week 7. It is not just the max OPR of each team. It allows us to consider the interaction of teams from different district/areas when they travel to different events. This takes care of the argument about stronger/weaker events when comparing across regionals/districts. Another way to look at the World OPR is how well each team do for the whole season. If a team starts off slow and improves in later weeks, the world OPR will be like an average of their whole season. The world OPR may not be the best indication of how a team would do. I personally use max OPR of each team in estimating what a team can potentially do at World.
