Verdict
STRUCTURALLY LOSING
Calibration is roughly neutral: actual win rate 24.8% vs implied 27.3% (-2.5pp). Picks track market expectations. Recent 30d (ROI +20.7%) is materially better than the prior 60d (-35.1%) — trending up, but expect mean-reversion.

⚠ Conflict / insider flags
- 2015 conduct charge: Found guilty of conduct prejudicial to racing by Racing NSW stewards for tipping two horses on TVN while backing another (Palazzo Pubblico) based on inside information from John Camilleri regarding Sam Kavanagh-trained horse. Received three-month suspension. Stewards did not find deliberate 'throwing off' but cited failure to disclose conflict. This occurred in January 2015; suspended September 2015.
- Was stood down by Sky Racing (then employer) during the charges and lost that position
Methodology: Form analysis; developed expertise in Sydney racing during his Telegraph tenure. Provides mounting yard tips and race-by-race analysis on Racing.com platforms.

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 | 258 | $-32.47 | -12.6% |
| Minus best 1 bet | 257 | $-42.47 | -16.5% |
| Minus best 2 bets | 256 | $-52.47 | -20.5% |
| Minus best 5 bets | 253 | $-77.47 | -30.6% |
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.
