Compare powerlifters across weight classes using Wilks, DOTS and IPF GL coefficients. Lift-by-lift breakdown and head-to-head comparison.
| Score | Lifter A | Lifter B |
|---|
Wilks 2020: score = total × 600 / (a + bx + cx² + dx³ + ex⁴ + fx⁵), where x is body weight in kg.
DOTS: score = total × 500 / (a + bx + cx² + dx³ + ex⁴). Body weight always in kg.
IPF GL points use the IPF Goodlift coefficients (raw classic, approximation).
