Verdict
STRUCTURALLY LOSING
Small sample (2 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 14.6% by -14.6pp — picks have negative skill relative to fair odds. Bayesian-shrunk ROI (regressed toward -13% population baseline by sample size) is -16.3% — a more honest expectation than the raw -100.0%.
Since last weekly snapshot: ROI: — · Shrunk ROI: +3.1% (-19.4% → -16.3%)
