Verdict
STRUCTURALLY LOSING
Calibration is negative: actual win rate 31.7% trails market-implied 51.9% by -20.2pp — picks have negative skill relative to fair odds. Recent 30d (ROI -15.3%) is materially better than the prior 60d (-36.7%) — trending up, but expect mean-reversion. Bayesian-shrunk ROI (regressed toward -13% population baseline by sample size) is -25.5% — a more honest expectation than the raw -28.5%.
Since last weekly snapshot: ROI: -1.6% (-27.0% → -28.5%) · Shrunk ROI: -0.8% (-24.6% → -25.5%)

What's driving the ROI?

Strip away the top winning bets and see how the picture changes — a stable record degrades gracefully, a lucky record collapses.

If stripping the top 2 wins materially changes the ROI, the headline number is being held up by a couple of fortunate longshots — not stable skill.
