It was mentioned in the first article that horses performances are rated in kilograms. Let us consider some examples:
(1) Horse A and Horse B dead-heat in a race when both are carrying 57kg. They have obviously run the same rating.
(2) Horse A and Horse B again dead-heat, but Horse A has 57kg and Horse B has 54kg. This time Horse A has rated 3kg higher than Horse B.
(3) Horse A and Horse B, both carrying 57kg, race against each other and Horse A finishes 4 lengths ahead of Horse B. How much better (in kg) is Horse A than Horse B? The answer depends on the distance of the race. After analysing many thousands of races I was able to devise a formula for converting lengths to kilograms:
To convert lengths to kilograms, multiply the lengths by 2000 and divide the answer by D, the distance of the race in metres.
In Example (3) above, the 4 length margin converts to kilograms as follows:
Race over 1000m: 4 times 2000 divided by 1000 is 8, so Horse A has rated 8kg higher than Horse B
Race over 1600m: 4 times 2000 divided by 1400 is 5, so Horse A has rated 5kg higher than Horse B
Race over 2000m: 4 times 2000 divided by 2000 is 4, so Horse A has rated 4kg higher than Horse B
(4) Horse A again beats Horse B by 4 lengths, but A has 57kg and B has 60kg (3kg more than A).
Race over 1000m: A is 8 minus 3, i.e., 5kg better than B
Race over 1600m: A is 5 minus 3, i.e., 2kg better than B
Race over 2000m: A is 4 minus 3, i.e., 1kg better than B
(5) Horse A wins Race 3 over 1400m in 82.0 seconds. Horse B wins Race 4 over 1400m in 83.0 seconds. Both horses carry 57kg. Track and wind conditions are identical in both races. How much higher is A’s rating than B’s?
In order to answer this, we need to come up with another formula. In examples (3)&(4), the formula relating lengths to kilograms was outlined and used. Now we need a formula for converting seconds to kilograms. This will be the subject of the next article. After that, we will be able to look at ways of using the Printout for the purpose of backing horses.
