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.
In the past I felt the average OPR was a reasonable indicator, and I would adjust the average OPR by an improvement factor over the season. And often teams would have lower OPRs at later events.

That's not the case this year. The improvement event to event has been dramatic. I think some teams have improved as much at 200% over 3 events. The average is really hit by how early a team first entered the season. Some teams that entered in Week 4 were much better simply by being able to watch earlier events. So this year we'll rely entirely on max OPR. However, I need to net out the coopertition OPR because it doesn't contribute to playoff scoring (or only at 10% of the 40 coop points at most.)

I'd say this year "as much as 200%" is even an understatement. I know we went from a capped 5 our first event to 3 full stacks now. And I know some teams have made even larger jumps (OPR jumps of 60+).

If you want this (or if anyone else does), we have an online OPR calculator that includes component OPRs and an overall OPR with coop and fouls already netted out (no coop for the exact reason you described). You can search for any event, division, or active team and it has team lists for every division sortable by highest no-coop OPR.

For example, the list for Newton is here.
