Verdict
STRUCTURALLY LOSING
Calibration is negative: actual win rate 40.6% trails market-implied 62.7% by -22.1pp — picks have negative skill relative to fair odds. Recent 30d (ROI -38.2%) is materially worse than the prior 60d (-1.1%) — trend is declining.
Since last weekly snapshot: ROI: +2.7% (-18.6% → -15.9%) · Shrunk ROI: +2.4% (-17.5% → -15.1%)

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.

Minus best 5 bets128$-42.18-33.0%

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.
