WHY THEY MOVED
Mairon Santos did not compete on this card. Across the Sep 11, 2026 → Sep 13, 2026 recalculation, CIR moved 71.38 → 71.37 (-0.01). Any rank movement came from field-wide results, normal time decay and eligibility changes rather than a new bout for Mairon Santos.
Card movement uses CIR v2.8 snapshots at 2026-09-11 and 2026-09-13. A rank can change because the fighter changes, other fighters change, eligibility changes, or evidence ages with time.

CAREER RATING TIMELINE
Every qualified historical snapshot in the CIR v2.8 archive, from Mar 9, 2025 through Sep 14, 2026.
This chart is descriptive historical output, not a prediction. Inactivity can lower CIR through time decay even without a new loss.
How to read this number
Opponent-relative fight evidence drives ability; reliability changes the weight of that evidence; recency ages it; and bounded, division-specific championship support combines with ability. Those context displays are not separate additive bonuses.
