DOTS Wilks and IPF GL Powerlifting Scores

On this page

Implementation sheet

DOTS, original Wilks, Wilks 2020, and IPF GL all adjust a powerlifting result for bodyweight, but they use different models. Use the formula named by the federation or dataset. Never compare a DOTS number directly with a Wilks or IPF GL number.

What each score does

Each model combines bodyweight with a total or result through a mathematical coefficient. The output is useful only inside the same formula version and input conventions.

DOTS is widely used in parts of the powerlifting community. Original Wilks remains familiar but is a legacy formula. Wilks 2020 is a separate update. The International Powerlifting Federation currently uses IPF GL for its official points calculations.

Why rankings can change

A scoring model is fitted to a reference population and makes different assumptions about how performance changes across bodyweights. Two models can therefore rank the same lifters differently, especially near the ends of their bodyweight distributions.

The IPF's published model evaluation compared several approaches and selected its GL system for official use. That does not turn DOTS or Wilks into invalid arithmetic; it defines which formula applies in IPF contexts.

Comparison rules

Use the same sex category and formula version for every score in a comparison.

Convert pounds to kilograms before applying a kilogram-based coefficient.

Keep the same equipment and competition context.

Name the data source and date when publishing percentiles or score bands.

Do not label a score elite or beginner without a defined population.

Which calculator to use

Start with the Powerlifting Total Calculator when you need the sum of squat, bench press, and deadlift. Use DOTS Calculator when the competition or dataset specifies DOTS. Use Wilks Calculator only for original Wilks in this package. Use an IPF GL calculator for current IPF points.
