Verdict
STRUCTURALLY LOSING
Small sample (1 bets) — anything below ~100 settled bets means CIs are wide enough to be near-useless. Calibration is negative: actual win rate 0.0% trails market-implied 9.1% by -9.1pp — picks have negative skill relative to fair odds. Bayesian-shrunk ROI (regressed toward -13% population baseline by sample size) is -14.7% — a more honest expectation than the raw -100.0%.

a lucky record collapses.
