Verdict
ROI MISLEADING
Small sample (41 bets) — anything below ~100 settled bets means CIs are wide enough to be near-useless. Calibration is roughly neutral: actual win rate 36.6% vs implied 34.3% (+2.3pp). Picks track market expectations. 516% of total P/L comes from just the top 2 winning tips. Strip them out and you'd see an ROI of -32.5% on 39 bets — the headline number is being held up by a couple of lucky longshots. Recent 30d (ROI +29.3%) is materially better than the prior 60d (-6.6%) — trending up, but expect mean-reversion. Bayesian-shrunk ROI (regressed toward -13% population baseline by sample size) is -3.8% — a more honest expectation than the raw +7.4%.

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.
| Subset | N | P/L | ROI |
|---|
| Full record | 41 | +$3.04 | +7.4% |
| Minus best 1 bet | 40 | $-8.66 | -21.6% |
| Minus best 2 bets | 39 | $-12.66 | -32.5% |
| Minus best 5 bets | 36 | $-22.56 | -62.7% |
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.
