RaceMetrics has added Form Temperature to every racecard. The feature scores a trainer's or jockey's performance over the last two weeks on a scale of 0–100, always measured against their own five-season record.

The logic is straightforward: what counts as a flying fortnight depends on who you are. Two winners from six runners means something different for a small yard than for a champion stable. Form Temperature accounts for that by rating each participant against themselves.

How to read it

On the racecard, you will see a coloured pill next to each trainer and jockey name:

  • Red — hot (95 or higher): a fortnight that good comes up by luck fewer than 1 time in 20
  • Amber — warm (75–94): a better fortnight than usual
  • Pale blue — cool (6–25): a quieter fortnight than usual
  • Blue — cold (5 or lower): the same rarity on the quiet side
  • No pill (25–75): normal variance, which is most fortnights — so the card stays clean

Hover the pill — or press and hold it on a phone — for the full story: the fortnight's record, the five-season benchmark it is being judged against, and how often a run like it happens by luck.

In the video above, on a Kempton fillies' novice: Simon and Ed Crisford carry a red 95, from seven winners in twenty runners (35%) against a long-run 19.1%. At the other end, John Gosden shows a blue 3 — two winners from twenty-seven, 7%, against a five-season 21.4%. That same 7% would be an ordinary fortnight for plenty of yards; for a stable of that strength it is a genuine lull, and that is the whole point of scoring everyone against themselves.

Where to find it

Form Temperature appears on the Ratings view, At-a-Glance, and on past racecards — where the score reflects the form position as it stood on race day.

A note on use

Back-testing shows that runners from hot yards do win more often than that yard's baseline suggests. However, the betting market has already priced in the same form. Use Form Temperature to understand why a stable is flying, not as a selection tool in itself.
