Verdict
STRUCTURALLY LOSING
Calibration is roughly neutral: actual win rate 21.8% vs implied 23.7% (-1.9pp). Picks track market expectations. Recent 30d (ROI -55.6%) is materially worse than the prior 60d (+9.4%) — trend is declining.
Since last weekly snapshot: ROI: -0.1% (-17.9% → -18.1%) · Shrunk ROI: +0.7% (-16.8% → -16.1%)

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 2 bets76$-28.10-37.0%
Minus best 5 bets73$-39.30-53.8%

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.
