Does OPR in this case refer to season-long OPR?

The OPRs here are calculated from Archimedes only, it does not include data from any previous event.

In the past, when looking at the data, some of the "deltas" have been indicators of interesting strategy. For instance, in 2010, 33 had a higher OPR than the number of actual points the team scored on average. This is because they primarily worked as a back and midfielder making passes into the home zone when they had a compitent home zone partner. This happened a lot at 2010 MSC that year where 2+2+2=8 or 3+2+1=10... Also that year, they had a very good win/loss record, but had a very low CCWM compared to many other high OPR teams. This was due to some concise strategy that because of the way ranking points were done that way, close high scoring matches were much more beneficial than blowing out an opponent, thus some matches you would use a a more cut throat strategy to ensure the win in a difficult match, but the next match might look like an easy victory, so you might use a much friendlier strategy so that your opponent could get a better score.

Even though it was incredibly dysfunctional, 2010 was a fun game for strategy. You hit the nail on the head, though. OPR can get thrown off by alliance partners and strategies. However, the biggest thing I noticed upon looking at the data is that OPR was surprisingly precise with totes, okay with cans and auto, and completely useless for litter.

It's tableau.
