Recent form

Figures from the official racecard, most recent run last.

7100

Numbers are finishing positions; a dash marks a season break and letters mark non-completions. Full past-race history is not available on the current data plan, so the model reads these figures rather than individual past runs.

Why this rating?

Every factor, its weight and how this horse scored against the field.
