Opening night scorecard: 5 winners from 12 races — including the one that got away

Two days ago we said we would publish our horse racing model's track record — wins, losses and all. Last night was the first real test of that promise: a 12-race card, three race series, and results we could not edit after the fact.

Here is the honest scorecard.

The numbers

Series	Races	Winners called	Quinella/Place hits
S1	4	1	4/4
S2	4	3	4/4
S3	4	1	3/4
Total	12	5	11/12

A 42% strike rate on winners, and 11 of 12 races where our top picks filled the quinella-place frame. For a model's first fully-public night, we will take it — but the details matter more than the headline.

What worked: the steam call

The best call of the night came in S2 Race 2. Our drift monitor flagged horse #2 with a -59.4% odds steam — the market was hammering it late, and our model agreed. It won. The Brier score for that race was 0.013, which is about as close to a perfect probabilistic call as you get.

This is why we watch odds movement in the final minutes: late money in Hong Kong racing is often smart money.

What didn't: the double-steam trap

S2 Race 4 looked even better on paper. Two horses steaming at once — #2 at -51.5% and #6 at -26.5%. We flagged both. The winner? #4. Neither steam horse even won.

That miss is worth more to us than the five winners. It tells us that when two horses steam simultaneously, the signal can cancel out — the market is split, and the model should widen, not narrow, its confidence. We have already logged it for the next retraining cycle.

Why we show you the losses

Any tipster can screenshot their winners. We would rather you see the full 12 races, because that is the only way you can judge whether 5/12 is skill or luck. Over a season, the calibration — not any single night — is what separates a model from a coin flip.
