Ratings are updated daily after racing concludes. Results from each day's racing are processed overnight, so you'll see updated ratings reflecting yesterday's results each morning.

RaceMetrics ratings are our proprietary performance measure. They track form over time – 1500 is average, 1550+ indicates strong performers, and 1600+ represents elite level. Ratings are updated daily each morning based on the previous day's results.

We track seven connection types: Horses, Trainers, Jockeys, Owners, and bloodlines (Sires, Dams, Damsires). Each profile includes full form analysis, ratings history, P/L tracking, and performance breakdowns.

RaceMetrics applies Elo ratings to UK and Irish horse racing. The system was built by Simon Walton, founder of Proform Racing Limited (a British racing software company established in Halifax, West Yorkshire in 1995), and rates every race that has run in Britain and Ireland across seven connection types — horses, trainers, jockeys, owners, sires, dams and damsires. Ratings are recomputed daily on Proform's full 25+ year dataset and surfaced at racemetrics.co.uk.

Horse racing Elo ratings work by extending the original two-player chess formula to multi-runner races. For each horse in each race, RaceMetrics computes the Elo expectation against the entire field — what percentage of rivals the horse would be expected to beat given its rating versus the field's ratings — then updates the rating once based on how the horse's actual finishing position compared to that expectation. The same machinery runs in parallel across seven independent rating pools: horse, trainer, jockey, owner, sire, dam and damsire.

To use Elo ratings for horse racing, look at two figures together: the horse's individual H rating (its own ability) and the Combined Score (a weighted average of the trainer, jockey, owner, sire, dam and damsire ratings). A strong H signals individual horse ability; a strong Combined Score signals an above-average support package around the horse. Historically the horse with the highest Combined Score in a race wins 22.97% of the time — 2.15 times the random-chance rate — across 25+ years of UK and Irish racing data.

PRB stands for Percentage of Rivals Beaten — a finishing-position metric used in RaceMetrics' Elo adaptation. PRB normalises finish position by field size. For example, a horse finishing 3rd in a 12-runner race has a PRB of (12-3)/(12-1) × 100 = 81.8%, having beaten 9 of 11 rivals. PRB is preferred over raw finishing position because it accounts for field-size differences and produces a continuous 0-100 metric suitable for Bayesian rating updates.

The Combined Score is RaceMetrics' weighted average of six connection-type Elo ratings: Owner 20%, Trainer 20%, Jockey 20%, Dam 18%, Sire 12%, Damsire 10%. The horse's own H rating is reported separately and is deliberately not folded into the Combined Score. The two figures answer different questions: H is about the horse's own ability; Combined Score is about the strength of the support package around it.

Patterns are saved from profile pages. When viewing statistics (e.g., a trainer's record at a specific course), look for the Save Pattern button. This creates a pattern with those conditions that will alert you when matching runners appear on racecards.

The System Builder is a betting-system back-tester. You build a system from a set of rules (filters), then test how those runners would have performed across UK and Irish racing back to 2018 - strike rate, A/E, ROI and profit/loss at Betfair SP - before refining it and tracking today's qualifiers.

The System Builder is a Proform Premium feature. It is currently in beta and is being rolled out gradually.

Back-tests run on resulted UK and Irish racing from 1 January 2018 onwards. Some specialist fields (sectionals, bookmaker prices, RaceMetrics ratings) start later and will raise the start date automatically with a warning.

P/L is shown to level stakes at Betfair Starting Price (with your chosen commission), alongside Industry SP and bookmaker prices. A/E (actual versus expected wins from the market) measures value independently of price.

RaceMetrics uses official racing data covering UK and Irish racing. Our database includes comprehensive historical performance data. P/L calculations use Betfair Starting Prices (BSP) for accurate profit tracking.

P/L shows the theoretical profit or loss if you had backed every runner to £1 stakes at Betfair Starting Price (BSP). This gives a standardised measure of value performance, removing the subjectivity of individual price judgements.
