# IPF GL

> 2020

- Equation: `GLP = total × 100 / (A − B × e^(−C × bodyweight))`
- Variables:
  - `GLP`: IPF GL points.
  - `total`: Lift total in kilograms. 3-lift or bench-only, matching the event.
  - `bodyweight`: Bodyweight in kilograms.
  - `A, B, C`: Published constants for sex, classic or equipped, and 3-lift or bench-only.
  - `e`: Euler’s number.

Official IPF relative scoring from the 2020 GOODLIFT / IPF GL document (PDF window May 2020–Dec 2023). IPF still uses these constants. Coefficient rounded to 6 decimals, then multiplied by the total. 100 points is the elite reference for that bodyweight. Separate constants for sex, classic or equipped, and 3-lift or bench-only.
