How this bit of fun works

The strength of each GFL, BFL and GDFL senior match is calculated from the current ladder positions of both teams and how closely matched they are. Competition levels overlap, so a leading BFL game can outrank a lower GFL game and a leading GDFL game can outrank a lower BFL game.

The top and bottom 33% of each ladder are treated as bands, rounded up to whole teams. A top-band versus bottom-band match receives no positive ladder or closeness bonus. A match between two bottom-band teams receives a 5-point penalty from its league base score.

Matrix score = average quality of the umpire’s best 6 senior appointments, plus 0.75 points for each senior field appointment where an observer was recorded. Premium observer weighting: Joshua James ×1.25, Davin Reid ×1.25. The observation bonus is capped at 6 points. A 2025 continuity bonus then adds up to 8 points, tapering from rank 1 to rank 27. This is unofficial and does not measure match-day performance.

Peer % measures who an umpire was appointed alongside. The top and bottom 30% cohorts are frozen from the Matrix before peer weighting is applied, avoiding a circular rerank. Each top-cohort co-umpire slot contributes positively, each bottom-cohort slot negatively and middle or unranked peers are neutral. The net percentage contributes up to plus or minus 4 Matrix points.

What the columns mean
Rank
The umpire’s current position after 2026 evidence, the hidden 2025 continuity adjustment and peer exposure are combined.
Field umpire
Field umpires with more than five combined GFL, BFL and GDFL senior appointments. Select a row to expand the umpire’s senior field season.
Matrix score
The final score used for ranking: 2026 evidence, reviewed anomaly corrections, the tapered 2025 continuity adjustment and the capped peer-exposure adjustment.
2026 evidence
Average strength of the umpire’s best 6 senior appointments, plus the weighted observation bonus and any reviewed manual correction.
2025 rank
The umpire’s supplied finishing rank from 2025. It contributes a tapered continuity adjustment.
Movement
How many positions the current Matrix rank is above or below the umpire’s 2025 rank.
Peer %
Net co-umpire exposure: top-30% peer slots minus bottom-30% peer slots, divided by all valid co-umpire slots. Positive is stronger peer exposure; negative is weaker.
Top 25%
Number of senior appointments ranked in the strongest quarter of all current GFL, BFL and GDFL senior games.
Best game
The highest-ranked senior appointment received. Lower is stronger; #1 is the strongest current game ranking.
GFL
Number of 2026 GFL senior field appointments.
BFL
Number of 2026 BFL senior field appointments.
GDFL
Number of 2026 GDFL senior field appointments.
Total
Combined 2026 GFL, BFL and GDFL senior field appointments.
Observed
Senior field appointments with a recorded observer. Standard observations add 0.75 points; configured premium observers receive extra weighting. The bonus is capped at 6 points.
