Sky Racing - Darren McAullay
Tipster dossier — settled-bet performance through 2026-07-14 20:15 UTC
Verdict
BREAK-EVEN / MARGINAL
Calibration is roughly neutral: actual win rate 34.1% vs implied 32.3% (+1.8pp). Picks track market expectations. 170% of total P/L comes from just the top 2 winning tips. Strip them out and you'd see an ROI of -2.9% on 265 bets — the headline number is being held up by a couple of lucky longshots. Recent 30d (ROI -10.4%) is materially worse than the prior 60d (+12.7%) — trend is declining.
Bio & context
Darren McAullay is Western Australia's premier race caller and a legendary figure in WA racing, having broadcast for over 40 years since 1981. Beyond his role as TABradio's lead race caller and host of the iconic "Inside Running" show on SENTurf, he serves as Executive Officer of the Western Australian Racehorse Owners Association (WAROA), creating a potential conflict of interest between his tipping activities and his advocacy role for all WA horse owners. He also operates Macmedia Marketing, his own media company.

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 | 267 | +$10.86 | +4.1% |
| Minus best 1 bet | 266 | $-0.64 | -0.2% |
| Minus best 2 bets | 265 | $-7.64 | -2.9% |
| Minus best 5 bets | 262 | $-27.04 | -10.3% |
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.
