How this is calculated
Published shares add up to 99.6% because each value is rounded. Effective Legends normalizes the field to 100% before applying inverse Herfindahl concentration. Status uses Top 3 field share: under 35% is open, 35–50% is moderately concentrated, and 50%+ is narrow. This describes participation and published finishes, not balance quality, matchup polarization, or player experience.
