Prize: prize fund of the race itself (not the horse's winnings) — by feel: small / medium / big, no exact figures.
Days not entered: computed from the history dates.
History: at least the latest race (slot 1) is required. Exception — a debutant (never raced): leave all slots empty, the model figures it out.
Fill in order: races 1 → 2 → 3 → 4 → 5, no gaps. No data for older ones — leave them empty (model slightly weaker). Not allowed: race 4 filled while race 2 is empty.
If the horse ran — fill BOTH fields: position AND “Beaten” (plus price). Finished → place + lengths. Did not finish → Pulled up / Fell / … in position AND “did not finish” in “Beaten”. Don't leave one without the other.
Didn't run in a slot: leave position “—” and “Beaten” empty — the model reads this as “no race”. Ran once → fill only slot 1, leave the rest empty. Debutant → all slots empty.
Trainer % and Jockey %: annual WIN percentage (wins only, no places — only winner).
Regional note (jockey): in India (and, less so, Australia) the jockey affects the result far more than in racing worldwide on average: the gap from average to top is huge, a strong jockey decides the race. Betting India/Australia with a strong jockey — set its % higher.
Beaten (margin): in horse LENGTHS. 0 = won · 0.125 ≈ head · 0.25 ≈ neck · 1 = one length.
Time not entered — and that's fine: speed is already captured by the key metric — the margin in LENGTHS. Time adds only a touch, and would also force you to enter the track condition. Time is secondary — don't worry.
