Verdict

ROI MISLEADING

Small sample (5 bets) — anything below ~100 settled bets means CIs are wide enough to be near-useless. Calibration is positive: actual win rate 40.0% beats market-implied 36.5% by +3.5pp — picks have measurable skill versus fair odds. 230% of total P/L comes from just the top 2 winning tips. Strip them out and you'd see an ROI of -100.0% on 3 bets — the headline number is being held up by a couple of lucky longshots.

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.
