Performance Factor

Syntax​

Performance Factor  distance[K]

Parameters​

  • distance: The distance of the race.
  • K: Optional. If the distance is in kilometers, append 'K' (e.g., 10K). If 'K' is omitted, the distance is assumed to be in miles.

Description​

Calculates and displays a performance factor score based on the runner's time and the race distance, relative to world-best performances.

Remarks​

This command must follow an Event command that provides the time. The calculation uses separate formulas for males and females, updated in March 2003. A world-best performance yields a score around 1000. The formulas are:

  • Male: PF = (141000 / t) × D^1.0631
  • Female: PF = (167000 / t) × D^1.0425

Where 't' is time in seconds and 'D' is distance in kilometers.

tip

Prefer using Age Grade as it provides up-to-date calculations.

Examples​

To calculate the performance factor for a 10K race:

Event               TIME
Performance Factor  10K

To calculate the performance factor for a 6.12-mile race:

Event               TIME
Performance Factor  6.12
