Each season from 2017-18 was hidden from Vesta and forecast with a model fitted only on the seasons before it, the same model that publishes today's forecasts (checked Tue 13 Oct 2026). These are the forecasts of past seasons, not the published ones: the public record of forecasts made before kick-off starts on 30 Sep 2026 and lives in Vesta's track record.
