OPR is what this team contributed to its own alliance's score, DPR what it allowed the opposing alliance, and CCWM the difference. All three are solved across every alliance at that event at once, so they do not depend on who the team was paired with — which win rate and average score both do.

Read them as rankings, not quantities. The fit column is honest about the precision: these explain roughly a third of score variance, and each team's figure rests on about five alliances. DPR can even come out slightly negative, which is the least-squares fit overshooting rather than a team causing negative points.

A team playing pure defense suppresses opponents instead of scoring, so it shows as low OPR and low DPR. That is why CCWM is the column to lead with — at the Mall of America event the undefeated winner ranked 6th on OPR and 1st on CCWM.

Top 12 of 13 distinct allies.

Sorted by elimination partnerships first, then by how often they played together. That order is the point: a qualification partner is a random draw, so playing with someone repeatedly says nothing about either team. An elimination partner was chosen in alliance selection — so even one says something, because it is either who picked them or who they picked.

The record is the pair's record in the matches they played together, which is the only record that describes the pairing rather than either team on its own.
