Sky Racing - Ben Walker
Tipster dossier — settled-bet performance through 2026-07-14 20:15 UTC
Verdict
STRUCTURALLY LOSING
Calibration is negative: actual win rate 26.2% trails market-implied 40.1% by -14.0pp — picks have negative skill relative to fair odds. Recent 30d (ROI -41.3%) is materially worse than the prior 60d (-24.6%) — trend is declining. Bayesian-shrunk ROI (regressed toward -13% population baseline by sample size) is -25.5% — a more honest expectation than the raw -29.2%.

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 | 172 | $-50.17 | -29.2% |
| Minus best 1 bet | 171 | $-58.77 | -34.4% |
| Minus best 2 bets | 170 | $-64.77 | -38.1% |
| Minus best 5 bets | 167 | $-78.37 | -46.9% |
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.
