Under the Hood: How Our Scoring System Works
Every racing fan has a system. Some swear by trainer form, others by speed figures, and some just have a feel for a horse. The beauty of the sport is that there's no single right answer.
At Smart Racecards, we built a tool that respects that diversity. Our scoring system isn't a "black box" that pretends to predict the future. It's a transparent, flexible engine designed to assist your judgement.
This post explains the philosophy behind it, the factors we measure, and how you can make it your own.
The Philosophy: A Starting Point, Not a Final Answer
Our system has two layers:
- The Smart Score. A default rating for every runner using a balanced set of weights. Think of it as the opinion of a knowledgeable, dataâdriven analystâa quick way to frame a race.
- Custom Scoring. The real power. You can adjust the weight of every factor to create a score that reflects your view of what wins races.
The Building Blocks: What We Measure
Our scores analyse a wide range of data points for each runner. Today, we focus on these key areas:
1) Core Performance Ratings
Industryâstandard figures that assess a horseâs past performances.
- RPR (Racing Post Rating): Performance rating for a single run.
- Topspeed (TS): Measures how fast a horse ran, adjusted for conditions.
- Official Rating (OR): The BHAâs handicap mark for a horse.
2) Recent Form & Fitness
How a horse has been running lately is a strong indicator of current wellbeing.
- Wins & places: We reward recent topâthree finishes.
- Recency:
- Last run †30 days â small fitness bonus.
- > 50 days off â layoff penalty, which increases if the horse has no previous wins after a break.
3) Trainer & Stable Form
An inâform yard moves marketsâand outcomes.
- 14âday stats: We use both strike rate and total wins, with an eye on sample size.
- Hotâtrainer boost: Extra credit when a trainerâs strike rate is > 20% in the last two weeks.
4) Specialist Factors (Horses for Courses)
Some horses thrive under specific conditions.
- Course (C), Distance (D), Course & Distance (CD): Proven success is rewarded with meaningful bonuses.
- Beaten Favourite (BF): A slight negative on its own, as context mattersâit can also indicate latent ability.
5) Equipment & Physical Clues
Small changes can make big differences.
- Firstâtime headgear: Blinkers, visor, or cheekpieces debut â positive intent signal.
- Second run after wind surgery: Often when benefits show mostâtreated as a contextual positive, not a guarantee.
6) The âXâFactorâ: Comment & Spotlight Analysis
We mine official race comments and Racing Post Spotlight text for signals.
- Positive cues: âstrong,â âin form,â âwell handicappedâ
- Negative cues: âpoor,â âdoubtful,â âslowâ
We normalise language (e.g., stemming/lemmatisation) so small wording differences donât hide meaning.
How the Smart Score Comes Together
Under the hood, each factor is normalised to a 0â100 scale, then combined using weights. Conceptually:
