Transparency score breakdown
A personal project run by one software engineer, trading as OddsLens (named on its Terms page). It says the model's ledger is append-only and mistakes are fixed forward. The JSON feed gives the running totals, daily profit and loss and the 20 most recent picks, not every pick. Not the same business as oddslens.io, a separate football and Betfair tool.
