The whole research process on one page, in the order most people read a race.
Form
What a horse has already done, and how much of it carries over to today.
Pace & draw
How a race is likely to be run, and whether the starting stall matters at this track and trip.
Market & prices
Reading odds as probabilities, what price movement does and does not tell you, and what "value" really means.
- Market movers: steamers & driftersWhy prices shorten and drift, how moves are measured, and why a steamer is information rather than a verdict.
- Fair odds & implied probabilityOdds as probabilities, the overround, stripping the margin to fair odds — and why any "fair" price is an estimate.
- Value in horse racingProbability versus price, worked through — plus model error, market efficiency and why a value price can still lose.
