You just hit a massive total at your meet — squat, bench, deadlift, all personal records. Then the results sheet comes out and someone lighter than you wins "Best Lifter." How? Because raw poundage isn't the whole picture. Powerlifting uses coefficient-based scoring systems to compare performance across different bodyweights, and depending on which federation you compete in, you're being judged by a completely different formula.
Three systems dominate the sport: Wilks, DOTS, and IPF GL. Each one has a different formula, a different history, and a different set of federations backing it. If you compete — or plan to — you need to understand how each one works, what your score actually means, and which one applies to your meet.
■Why Powerlifting Needs Scoring Systems
A 600 lb deadlift means something very different coming from a 132 lb lifter versus a 275 lb lifter. Raw total alone can't tell you who the stronger athlete is relative to their size. Coefficient systems solve this by converting your total into a bodyweight-adjusted score, creating a level playing field across weight classes.
The goal of any good formula is accuracy across the full bodyweight spectrum — from the lightest competitors to the super heavyweights. That's where the systems diverge, and why Wilks was eventually replaced.
■The Wilks Score: Where It Started
The Wilks formula, developed by Robert Wilks (CEO of Powerlifting Australia) in 1996, was the sport's first widely adopted coefficient system. It uses a 6th-order polynomial equation with separate coefficients for men and women to produce a bodyweight-adjusted score from any lift total.
The formula looks like this:
Wilks = Total (kg) × 500 / (A + Bx + Cx² + Dx³ + Ex⁴ + Fx⁵)
Where x is bodyweight in kilograms and A–F are gender-specific constants.
Wilks worked well enough for decades — but it had a structural flaw. The formula was calibrated using 1990s competition data, which means it reflected the lifters competing at the time: primarily mid-weight competitors. At the extremes of the bodyweight scale — lifters under 52 kg or over 120 kg — Wilks produced skewed results that systematically favored middleweights and penalized heavier athletes.
It still appears in some legacy federations, but both major US federations (USAPL and USPA) have moved on.

■The DOTS Score: The Modern Replacement
DOTS (named for the shape of the data points used to build the regression model) was introduced in 2019. The formula uses a 4th-order polynomial and was calibrated using thousands of modern competition results — a much larger and more representative dataset than Wilks ever used.
DOTS = 500 ÷ (A + Bx + Cx² + Dx³ + Ex⁴) × Total (kg)
The key improvement: DOTS is more accurate at extreme bodyweights. Lighter lifters under 60 kg and heavier lifters over 120 kg get a fairer score than they would under Wilks. The formula doesn't artificially favor a specific weight class.
DOTS is now the official "Best Lifter" scoring system for USAPL and USPA, the two largest powerlifting federations in the United States. If you compete in either of those organizations, DOTS is your number.
DOTS can also be applied to individual lifts, not just totals — useful for comparing a single squat or deadlift across bodyweights.

■The IPF GL Points: The Strictest Standard
IPF GL (International Powerlifting Federation — Good Lift) points launched officially in May 2020 as the IPF's proprietary scoring system. It's the most comprehensive of the three formulas.
Where Wilks and DOTS produce a single coefficient for men and women, IPF GL goes further: it accounts for bodyweight, gender, and equipment type separately (raw versus single-ply equipped). Raw lifters and equipped lifters cannot be compared on IPF GL, which is by design — the physiological demands and performance ceilings differ enough that a single formula would be misleading.
IPF GL only applies to totals, not individual lifts. This is a notable limitation compared to DOTS and Wilks, but the IPF's own evaluation (2020) ranked IPF GL first in accuracy, with DOTS second and Wilks a distant third.
Every IPF-affiliated federation worldwide uses IPF GL. That includes USAPL when competing under IPF sanction at the international level.

■Wilks vs DOTS vs IPF GL: Side-by-Side Comparison
| Feature | Wilks | DOTS | IPF GL |
|---|---|---|---|
| Introduced | 1996 | 2019 | 2020 |
| Formula type | 6th-order polynomial | 4th-order polynomial | Multi-factor polynomial |
| Applies to | Individual lifts or total | Individual lifts or total | Totals only |
| Equipment adjusted | No | No | Yes (raw vs equipped) |
| Accuracy at extremes | Poor | Good | Best |
| Primary federations | Legacy feds | USAPL, USPA | IPF + all affiliates |
| Dataset | 1990s results | Modern competition data | Modern IPF data |
The scores are not interchangeable. A DOTS score of 400 does not equal a Wilks score of 400 — the scales, coefficients, and data behind each formula are entirely different. Never compare your Wilks score to someone else's DOTS score as if they're the same unit.
■What Is a Good DOTS Score?
DOTS is the most commonly referenced scoring system in American powerlifting right now, so knowing where you stand on that scale is practical.
| DOTS Score | Level |
|---|---|
| Under 200 | Beginner |
| 200–300 | Novice |
| 300–400 | Intermediate |
| 400–500 | Advanced |
| 500–550 | Elite |
| 550+ | World-class |
Most recreational lifters who train consistently for 1–2 years land in the 250–350 range. Hitting 400 puts you in genuinely advanced territory for your weight class. The 500+ range is where national-level competitors live.
■What Is a Good Wilks Score?
If you're reviewing older meet results or competing in a federation that still uses Wilks, these are the standard benchmarks:
| Wilks Score | Level |
|---|---|
| ~120 | Beginner |
| ~200 | Novice |
| ~238 | Intermediate |
| ~326 | Advanced |
| ~414 | Elite |
These are approximate thresholds — Wilks scores shift depending on bodyweight due to the formula's known inaccuracies at extremes. A 120 kg lifter at "326" is not directly comparable to an 82 kg lifter at "326" the way DOTS attempts to be.
■What Is a Good IPF GL Score?
IPF GL uses a different scale entirely — scores are generally lower in absolute number compared to Wilks and DOTS.
| IPF GL Points | Level |
|---|---|
| 70–80 | Intermediate |
| 80–90 | Advanced |
| 100+ | Elite |
| 120+ | World-class |
Because IPF GL separates raw and equipped, these benchmarks apply within each equipment category. An equipped lifter's 100 points is not directly comparable to a raw lifter's 100 points.
■Which Scoring System Should You Use?
The answer depends entirely on which federation you compete in — you don't get to choose.
Compete in USAPL or USPA? Your "Best Lifter" award uses DOTS. Track your DOTS score as your primary performance metric.
Compete in the IPF or any IPF affiliate internationally? IPF GL is your official system. Your DOTS score is irrelevant at those meets.
Reviewing older results or competing in a legacy federation? Wilks is what you'll see. Understand the limitations — particularly if you compete outside the 74–93 kg range where Wilks is most accurate.
Tracking personal progress regardless of federation? DOTS is the most practical choice for self-comparison over time. It's the most accurate coefficient for the broadest range of bodyweights, easy to calculate, and applies to individual lifts or totals.
Note: You can run all three scores on your current numbers and use whichever is relevant to your competition context. There's no rule against tracking all three — just don't cross-compare them as equivalent units.
■The Bottom Line on Powerlifting Scoring Systems
Wilks built the foundation for bodyweight-adjusted scoring in powerlifting, but its age and calibration on outdated data left it obsolete. DOTS improved accuracy across the weight spectrum and is now the standard in American powerlifting. IPF GL goes furthest — adding equipment adjustment and leading the IPF's global competition structure.
The right system is the one your federation uses. But if you want to benchmark your own strength development over time, DOTS gives you the most reliable signal across the widest range of bodyweights.
