Method correction · 9 September 2026. These are archived exploratory results, pending a rebuilt decision ledger. The legacy outfield score uses goals and assists; the goalkeeper score uses minutes. Neither establishes defensive or goalkeeping quality. Cost percentiles do not establish value for money. Euro Deal Alpha has been withdrawn because its monetary conversion is unsupported. Original experiment outputs remain preserved.

Historical club scorecards — exploratory archive

Recorded outcomes ranked within the original window, position, market-value and destination-tier pools. These scores describe the selected historical sample; they are not validated recruitment grades. The original Grade 1 experiment and later exploratory layers have different registration status.

Intervals describe sampling uncertainty under the legacy method. Of 79 clubs, 8 intervals exclude 50 before accounting for multiple comparisons. An interval containing 50 does not establish equivalence to random recruitment; an interval excluding it does not establish scouting skill.

The scorecard

Legacy score = median within-pool outcome percentile. Hit = share clearing the original success threshold. Cost = median fee percentile, excluding unpriced deals. These are separate descriptions; combining their ranks does not measure economic efficiency. Euro alpha is withheld pending a valid valuation method.

Exploratory clusters — not validated recruitment intent

Four clusters were fit to pre-transfer features. Reported subsample ARI (0.96) measures partition stability, not whether these names capture recruitment intent. Choosing four clusters also used observed outcome differences. The medians below are sample descriptions, not separate zero-skill benchmarks.

TrancheMeaning at signing timenMedian Grade 1

GAMBLEunproven, still paid up29756.5
VALUE-VETproven, acquired cheap49146.1
FILLERunproven/unused, near-free46039.2

Differences between these groups may reflect price, data coverage, opportunity and the outcome definition. The lower observed score for young players does not by itself quantify methodological bias or establish their correct benchmark.
