Verdict
STRUCTURALLY LOSING
Calibration is negative: actual win rate 23.6% trails market-implied 29.0% by -5.4pp — picks have negative skill relative to fair odds. Recent 30d (ROI -45.9%) is materially worse than the prior 60d (-4.4%) — trend is declining.

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.
