Method and data

The score uses the verified three pair intersections and four main–parent–grandparent relationship-group intersections. It is the character-only base total; a specific Veteran lineage can gain additional points from shared G1 wins.

Compatibility data sourced from the independently operated U-tools compatibility rankings. Local dataset updated August 25, 2026.
