Trap Bias

The draw, with
the context it deserves.

A raw trap win percentage is only the start. Read the advantage against fair share, compare distances and see how the pattern changes over time.

The same draw. A different distance.

Real data · Monmore
Monmore: each trap’s share of wins minus its fair share, by distance, 11 September 2024 to 11 September 2026. Bold means a clear bias (at least 1.5 points and 2.5 standard errors); the rest is inside noise.

Inside Trap Bias

Built for the next question.

Fair share, not a fixed sixth

Each trap is measured against its share of the runs, so a trap that is often empty is not flagged as a bias.

Distance and grade splits

Inspect the trap-by-distance matrix and race-class breakdowns, with thin samples omitted.

Short and long windows

Compare the bias across observation windows, then explore track records, standard times and local rating performance.

One runner / A connected research journey

From a name on the card
to a story worth following.

Try each step with Common Canter, the top-rated dog in the 13:17 at Monmore on 15 Aug 2026. It won at a Betfair SP of 5.00; the next race on the card did not go our way, and the demo shows both.
