Definitions

  • the present invention relates to methods and systems for calculating speed rating for participants in a speed contest or race. More particuarly, the present invention relates to methods, systems and formula for determining a speed value or speed rating for participants, such as race horses, in a speed contest, such as a horse race, for example.
  • a speed rating of a race horse is a comparative rating of the speed of the particular horse compared with the optimum speed for the particular race, taking into account the distance, in furlongs, of the race.
  • An animal's ability to race is a function of this innate ability modified by his physical condition at the time of the race. That is, an animal in peak physical condition can run over a given distance at a certain average speed, taking into account that the particular animal is, at the time, running the distance at its ultimate capacity and no further amount of training can improve its performance.
  • the innate ability to race for the individuals of any species has a bell shaped curve, the same as all other physical and performance characteristics, such as height or intelligence.
  • the individuals of a species tend toward a norm, that is, the peak of the bell shaped curve, with exceptional individuals of the species out at the tails on either end of the bell.
  • the racing class of a horse is related to his position on the bell shaped performance curve.
  • a horse of high class a horse whose position on the curve is out on the high side of the bell, will beat a horse of average class, a horse whose position on the curve is at the peak of the bell at any typical racing distance.
  • Higher class horses appear to have more ability and tend to perform better than lower class horses at all racing distances.
  • the problem is how to rate a horse's racing ability such that:
  • this equation is substantially accurate and effective for deriving the speed rating (SR) for race distances up to nine furlongs, a mile and 1/8.
  • SR speed rating
  • this equation is employed to obtain or derive a speed rating for horses racing at distances in excess of nine furlongs, the speed rating obtained falls short of plotting a substantially straight line curve for races over 9 furlongs.
  • the present invention provides another equation for solving the speed rating (SR) of a horse, which equation is more effective when applied Lo races having a distance of more than nine furlongs.
  • the equation is: Where f is the length of the race in furlongs. Where t is the time of the winning horse in seconds.
  • This formula may be used to calculate the speed rating (SR) of the winning horse, and when used on a horse holding dirt track records, an essentially straight line curve is generated which declines linearly as a function of the length of the race.
  • SR speed rating
  • the method of the present invention includes the steps of classifying the entrant relative to other entrants in the same or similar sporting events.
  • the speed rating of the entrant is calculated according to the mathematical formula shown above, which formula includes the pertinent factors for determining a speed rating for each entrant independent of varations such as track and classification of the entrant.
  • a speed rating is calculated which is general in its application in that the same speed rating applies for the entrant regardless of the distance of the race to be run.
  • the apparatus of the present invention includes means for data entry such as a keyboard similar to keyboards commonly used by 4-function arithmetic calculators, a random access memory for storing input data and other intermediate and output data, an arithmetic unit for calculating a speed rating given the input data, a display device for displaying selected data, and a read-­only storage program control for controlling the sequence of steps to be executed in the calculation of a speed rating.
  • means for data entry such as a keyboard similar to keyboards commonly used by 4-function arithmetic calculators, a random access memory for storing input data and other intermediate and output data, an arithmetic unit for calculating a speed rating given the input data, a display device for displaying selected data, and a read-­only storage program control for controlling the sequence of steps to be executed in the calculation of a speed rating.
  • a horse's racing class is related to this position on the bell shaped performance curve.
  • a horse of high class (out on the high side tail of the bell) at any typical racing distance. Higher class horses tend to perform better than lower class horses at all racing distances.
  • the problem is how to rate a horse's racing ability such that:
  • the focus is on the time of the race. If the average winning times of horses of the same class are plotted as a function of the distance of the race, the resultant curve is nonlinear, however, if the average speed is plotted as a function of distance, the resultant curve is a straight line below 9 furlongs and a straight line at a different slope above nine furlongs. This relationship is shown in Fig. 1 for North American Records at distances from 6 furlongs to 16 furlongs. Research on the speed-­distance characteristics of all classes of race horses from distance of 5 furlongs to 1 1/2 miles has confirmed that all classes of horses exhibit the same straight lines (linear) relationships: of average speed versus distance.
  • Fig. 1 illustrates the generator of the speed rating system.
  • the ordinate is the average speed over the distance.
  • the abcissa is the distance in furlongs.
  • the desire is to make a scale of 0-100 where the vast majority of all performances will fall within that scale.
  • the rating of 100 is chosen as follows: an optimum speed at 9 furlongs is 5 lengths per second (this is approximately the North American Record - See Fig. 2) this is assigned a speed rating of 100, the minimum speed at 9 furlongs is assigned a speed rating of 0.
  • the 100 speed rating line is then drawn for the ordinate 5 with a slope of (-0,0465). Each 0,08 length/sec. at 9 furlongs reduces the speed rating by 10 until a speed rating of 0 is achieved.
  • Fig. 1 illustrates the generator of the speed rating system.
  • the ordinate is the average speed over the distance.
  • the abcissa is the distance in furlongs.
  • the desire is to make a scale of 0-100 where
  • the problem now is to generate the speed rating as a continuous function of the average speed of the runner at the distance.
  • Equation 1 then relates the speed rating as a function of time and distance over 9 furlongs.
  • the equation shown above may be executed by a special purpose digital computer or be a sequence of program steps executed on a general purpose digital computer.
  • an electronic speed rating calulator 10 may be packaged as a hend-held calculator having function keys 12, 13 14 and 15 for identifying the data to be entered on data entry keys 16.
  • a display 18 is included to provide visual display of input data and speed rating result.
  • the speed rating calculator includes data input means which could be keyboard 12-16.
  • the data entry means is connected to arithmetic unit which executes arithmetic functions in the calculator and to random access memory for storage of entered data.
  • Program control read-only storage controls the sequence of arithmetic and logic functions performed by the calculator. Control and timing logic interacts with all other inputs, data input means, arithmetic unit, random access memory, and display to control execution of the speed rating calculation.
  • the first step is a data entry.
