WORKED HORSE RACING EXAMPLES

From the numbers
to the decision.

Four realistic examples. Every assumption, formula and result is shown so you can reuse the method with your own race.
01 · SINGLE-RACE EXOTIC

Price a 4-horse Exacta box

How much does a $1 Exacta box cost when you use horses 2, 4, 6 and 8?

  1. State the inputsWrite down exactly what you know or estimate.
  2. Run the calculationKeep cost, probability and performance mathematically separate.
  3. Interpret the outputUnderstand what the number says—and what it cannot promise.
