Tipster dossier — settled-bet performance through 2026-06-05 22:16 UTC

Verdict
STRUCTURALLY LOSING
Calibration is negative: actual win rate 25.1% trails market-implied 29.8% by -4.7pp — picks have negative skill relative to fair odds. Recent 30d (ROI -9.0%) is materially better than the prior 60d (-24.8%) — trending up, but expect mean-reversion.

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.
