Key Race

Previous race that produced multiple subsequent winners — form from this race is reliable.

Lead by many Lengths

Speed Rating Foundation

The average NSR from a horse's best three recent runs, used as the foundation for fair odds calculation. Can be manually adjusted in the Overrides section.

Bend Position

Position of the horse at the turn during the race.

Race Status: Low Confidence

Thin data, many debutants, or inconsistent form. Treat outputs with care.

Race-level Analytical Confidence

A percentage reflecting how complete and consistent the form data is for this race. High confidence means the model has sufficient data to differentiate runners. Low confidence signals a wide-open or data-thin race.

Days Since Last Run

Number of days between the horse's most recent run and today's race.

Early Speed Index

A composite score measuring how aggressively a horse contests the early part of a race, relative to the field.

Model-Derived Win Probability

The probability of winning expressed as decimal odds. Derived from NSR, form, pace, and trainer/jockey data. Represents what the price should be without bookmaker margin.

Lengths Behind Winner

The official margin in lengths that a horse finished behind the race winner. Used to calculate NSR adjustments.

Race Status: Maximum Confidence

Strong separation between runners, reliable form data throughout the field.

Normalised Speed Rating

A single number representing how fast a horse actually ran, adjusted for track, distance, going, and class. Higher is better. Enables comparison across different races and venues.

Official Rating

The handicapper's numerical assessment of a horse's ability, used for weight allocation in handicaps.

Market price longer than Fair Odds

The bookmaker is offering more than our model says the horse is worth. Represents potential value.

Penetrometer Reading

Official track going assessment — measures the firmness of the ground.

Race Status: Standard Confidence

Reasonable data but some uncertainty. Use alongside other angles.

Market price shorter than Fair Odds

The bookmaker's price is shorter than the model probability. The horse is overbet relative to its chance.

The inner training track at the racecourse. Workouts here are generally more controlled and closely observed by trainers.

Optimum Body Weight — derived from past wins and close finishes. A useful fitness and condition benchmark.

The outer training track. Horses allowed on the outer sand are often closer to race fitness.

How fresh and primed the horse appears based on its workout pattern relative to race day. High readiness = well-tuned for this run.

A composite rating of the horse's recent trackwork quality, derived from timed gallops on inner and outer sand.

How the horse's trackwork rating compares to others in today's race field (standard deviations from field mean).

How today's trackwork compares to this horse's own recent workout history (standard deviations from its own baseline).
