FC Erzgebirge Aue

This archive’s Success Index combines KP (40%), MS (20%) and GO (40%). Knockout qualification and group / unique group qualification receive equal weight. KP includes qualifying rounds as well as later knockout rounds; the index does not separately adjust for opponent strength. These are editorial weights, not an official UEFA rating. Only principal competitions are included. Each component is calculated before rounding.

Only measures with eligible records are used here. Their weights are redistributed proportionally: MS 33.3% · KP 66.7%. Missing records do not count as zero; profiles with different available measures are not directly equivalent.

MS = (2 × wins + draws) ÷ (2 × scored matches) × 100. Includes group and unique group matches. Results after extra time count; shoot-out goals do not. Awarded results count in totals, but are excluded from biggest-result records.

KP = successful Romanian qualification outcomes ÷ confirmed knockout encounters × 100. A success means the Romanian club qualified for the next round; in a final, it means the Romanian club won the trophy. Each whole tie or final counts once, including qualification decided by penalties, away goals or an additional match. Group and unique group stages are excluded.

GO = (Q + 0.50 × S + 0.25 × D) ÷ (Q + S + D + N + O) × 100. Q means only the Romanian club qualified in the same competition; S means both qualified there; D means the Romanian club transferred to another competition, regardless of its opponent’s outcome; N means neither continued; O means only the opponent continued. If the Romanian club qualified in the same competition while the opponent transferred, the comparison is Q.

Each Romanian club–opponent comparison counts once per group / unique group phase, regardless of the number of matches. A country total sums those opponent comparisons, not distinct group appearances. Different opponents in a unique group may have faced different schedules. Ongoing and unconfirmed outcomes are excluded. Sample sizes appear beside each score; small samples can produce extreme values. Goals are reported separately.
