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 Euro Deal Alpha has been withdrawn because its monetary conversion is unsupported.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.

The Juventus ledger — historical results under review

The archived median score is 48.79, with reported interval [32.4–62.9]. That result does not show Juventus recruits equivalently to random selection. Its fee and wage-proxy percentiles also do not establish overpayment. The tables below preserve the historical calculations while decision dates, outcome measures and economics are reconciled.

Every fee, on one plane

Grade 1 percentile (y) against fee cost percentile within pool (x) for the 28 fee-bearing decisions; rows without a fee-cost percentile sit on the right rail. Colour = fitted tranche: WIN-NOW GAMBLE VALUE-VET FILLER. Hover for detail.

Deal Alpha — monetary claims withdrawn

The previous calculation multiplied excess goals and assists against sampled fee-constrained baskets by a fee-to-output ratio. That does not establish euro value, especially for defenders. The historical calculations remain archived; these monetary bars and club rankings are withheld. A replacement benchmark must measure relevant football output at comparable commitment and task, with held-out validation.

The historical wage-cost proxy

The table's annual proxy is fee divided by four plus a recorded gross wage. Four years is an assumed constant, not each player's actual contract. This is not total contractual commitment or a complete financial return. Wages can be estimates, loan fees can be missing, and sale proceeds alone do not establish profit. All economic verdicts remain unresolved pending the financial ledger.
