Realized edge +3.1 probability points across 124 scored resolved positions, 95% CI [-5.0, +11.8]. These figures describe the recent-trade window this read covered, not the wallet's whole resolved record, so they cannot be read as an edge either way. A Convexly read of the public record.

Diagnostics on public behavior, not investment advice. Demonstrated past skill is not a forecast. The figures describe the window this read covered, which omits redeemed positions and is not the full resolved record. This caveat travels with the badge in every view.
