📊 Placepot

Once odds have been loaded for a meeting's races, the Placepot tab finds the most likely placed horses across the card to help you build a perm.

  1. Load a meeting's PDF and add odds — using Live Odds or by pasting — for the races you want to cover.
  2. Tap Placepot and the highest-chance runners for each leg are generated automatically.
  3. Check the Monte Carlo view to see how often each horse places across 10,000 simulated runs.
  4. The Nap of the Day flags the model's strongest single banker across the meeting.
Monte Carlo simulation
The simulation runs each race 10,000 times using the model's probabilities, then counts how often each runner places. It turns a single probability into a distribution — so you can see which selections hold up and which are closer to coin-flips.
💡 The Nap of the Day is drawn from the first six races and uses a slightly different weighting to the main prediction screen, so its percentage may read a little differently for the same horse.

🍀 Lucky 15

A Lucky 15 is 15 bets across 4 selections: 4 singles, 6 doubles, 4 trebles, and 1 four-fold. Load one or more meetings and the Predictor will find the strongest combination.

  1. Load PDFs from the meetings you want to use. The Lucky 15 selects one horse from each of four different races, across different meetings if you like.
  2. Tap Lucky 15 in the navigation. Enter your stake per unit and choose WIN or E/W.
  3. For E/W, select ¼ or ⅕ place terms to match your bookmaker. Note: your total stake is 30× the unit — a £0.50 E/W unit = £15 total.
  4. Tap ⚡ Find Best Lucky 15. The model picks one horse from each odds band — keeping the combination balanced.

💡 Understanding the Prediction

The percentage shown beside each horse is the model's estimated probability of winning, built from historical form, class, speed figures, trainer and jockey performance, course suitability, current betting odds and other statistical factors.

Confidence rises when several of these factors agree on the same horse, and eases when the race looks more open and chances are spread across the field.

A higher percentage means the model believes the horse has a better chance than its rivals. It is not a guarantee — horse racing will always contain uncertainty.
