Raza point score system

The Raza point score system is a method in Paralympic athletics field competitions for comparing throws or jumps by athletes of differing levels of disability. In events where athletes of multiple different classifications compete, performances are converted to point scores by a formula which accounts for the athletes' classifications. This means that a more disabled athlete may beat a less disabled competitor with a slightly shorter throw or jump.

The formula is a Gompertz function:

${\displaystyle {\text{points}}=q=ae^{-e^{b-cp}}}$

Where ${\displaystyle p}$ is the performance in metres, and ${\displaystyle a}$, ${\displaystyle b}$, and ${\displaystyle c}$ are constants. Presently^[update], ${\displaystyle a}$ (the maximum possible score) is 1200 points in all cases, ${\displaystyle b}$ varies between events (with men's and women's events of the same discipline having different values), whilst differing values of ${\displaystyle c}$ distinguish the different classifications for each event. These constants are reviewed by the International Paralympic Committee annually. The constants are set such that the world's best athletes will achieve scores of around 1000 points.
