For decades, the Wilks coefficient was the standard way to compare powerlifters of different bodyweights. Then, in 2019, two major federations — USAPL and the IPF — both dropped it in favor of newer systems (DOTS and IPF GL Points respectively).
Understanding why Wilks was replaced — and how the replacement systems work — gives you a clearer picture of how your strength is actually being evaluated in competition.
What Is the Wilks Score?
The Wilks score is a number that represents a powerlifter’s total weight lifted (squat + bench + deadlift) adjusted for bodyweight. It was developed by Robert Wilks of Powerlifting Australia and became the dominant scoring method in international powerlifting for roughly two decades.
Like all bodyweight-adjusted coefficients, Wilks answers the question: “Given this person’s bodyweight, how impressive is their total?” A lifter with a higher Wilks score is considered relatively stronger than one with a lower score, regardless of how different their absolute totals are.
Formula: Wilks Score = Total (kg) × Coefficient
The coefficient is derived from a 5th-degree polynomial equation using the lifter’s bodyweight (in kg) and sex. Each sex has separate polynomial constants that define how strength should scale with bodyweight for male and female lifters.
What Is DOTS?
DOTS (Dynamic Objective Team Scoring) is the system that replaced Wilks in USA Powerlifting (USAPL) and USPA beginning in 2019. Like Wilks, it multiplies a coefficient derived from a polynomial equation (using bodyweight and sex) by the lifter’s total.
The key differences are in the specific coefficients and the underlying data used to build the polynomial. DOTS was developed with more modern data and was specifically designed to address the known inaccuracies in Wilks at the extremes of the bodyweight spectrum.
Wilks vs DOTS: The Core Difference
Both systems use the same basic approach — polynomial coefficient × total — but the coefficients produce different results, particularly at lighter and heavier bodyweights.
The main criticism of Wilks was that it systematically favored heavier weight classes over lighter ones. Analysis of competition data showed that in Best Lifter competitions scored with Wilks, heavier weight classes won disproportionately often compared to what you’d expect from random distribution. The lightest weight classes were statistically disadvantaged.
DOTS was designed to correct this. Multiple independent analyses comparing actual competition results have found DOTS to produce a more uniform distribution of Best Lifter winners across weight classes — a sign that the scoring is more equitable.
Side-by-Side Comparison
| Feature | Wilks | DOTS |
|---|---|---|
| Introduced | 1990s | 2019 |
| Developer | Robert Wilks (Powerlifting Australia) | Developed for modern federation use |
| Primary federations | Legacy; smaller/older feds | USAPL, USPA |
| Equipment-specific coefficients | No | No |
| Designed for | All powerlifting (original); raw increasingly | Raw (unequipped) lifting |
| Known issue | Under-rewards lighter weight classes | More balanced across weight classes |
| Still used competitively | Yes (some feds, historical comparison) | Yes (active use in USAPL/USPA) |
The Third Option: IPF GL Points
When the IPF dropped Wilks in 2019, they chose a third path rather than adopting DOTS. IPF GL Points were designed with several features DOTS lacks:
- Equipment-specific coefficients: Separate formulas for raw and equipped lifting, acknowledging that equipment changes the strength-to-bodyweight relationship
- Lift-specific coefficients: Separate formulas for squat, bench press, deadlift, and total, rather than a single formula applied to the total regardless of lift
The IPF argument was that DOTS, like Wilks, applies a generic coefficient to the total — which means it doesn’t account for the fact that a light-class lifter might have a relatively weak bench compared to their squat and deadlift. IPF GL Points are more granular.
In practice, both DOTS and IPF GL Points are considered significant improvements over Wilks. The choice of which to use comes down to which federation you’re competing in.
Which System Is More Accurate?
This depends on what “accurate” means. If the goal is a uniform distribution of Best Lifter awards across weight classes, DOTS outperforms Wilks and performs comparably to IPF GL Points in most analyses.
If the goal is accounting for equipment type and individual lifts rather than totals only, IPF GL Points is more comprehensive.
For practical purposes — if you compete in USAPL or USPA, your score is DOTS. If you compete in IPF or an IPF affiliate, your score is IPF GL Points. Historical records in Wilks are still useful for comparison with older data but are no longer the competition standard at the major federation level.
How to Calculate Wilks Score
If you want to calculate your Wilks score for historical comparison or for a federation that still uses it:
Step 1: Convert your bodyweight and total to kilograms (divide pounds by 2.205).
Step 2: Use the polynomial equation for your sex to generate the Wilks coefficient from your bodyweight. Most calculators do this automatically.
Step 3: Multiply the coefficient by your total in kg.
Example: A male lifter at 82.5kg bodyweight with a 700kg total. The Wilks coefficient for an 82.5kg male is approximately 0.5845. Wilks score = 700 × 0.5845 = 409.2.

For historical comparison, these are the approximate Wilks score tiers for raw SBD total:
| Level | Wilks Score |
|---|---|
| World Class | 526+ |
| Elite | 488–526 |
| Advanced | 421–488 |
| Intermediate | 359–421 |
| Novice | 295–359 |
| Beginner | 217–295 |
Note: These benchmarks were developed against IPF-aligned scoring data. Because DOTS produces numerically higher scores than Wilks for the same total, you cannot directly compare Wilks and DOTS numbers — a Wilks score of 400 does not equal a DOTS score of 400.
Does Wilks Score Still Matter?
For active competition in USAPL, USPA, and IPF, Wilks is no longer the scoring system. However, it still appears in:
- Historical records: Performances before 2019 are recorded in Wilks. Comparing yourself to historical bests often requires converting to the same system.
- Smaller federations: Some regional and single-state federations still use Wilks, especially those that haven’t updated their bylaws.
- Personal tracking: Some lifters continue to track Wilks alongside DOTS for continuity across their career.
- The OpenPowerlifting database: Records from before 2019 include Wilks; newer records include DOTS. Both are available for comparison.
Frequently Asked Questions
Is a higher Wilks score better than a higher DOTS score?
You can’t compare the two directly — they’re different scales. What matters is your score relative to others using the same system. A DOTS score of 450 and a Wilks score of 400 might represent similar relative strength levels, but comparing the raw numbers is meaningless.
Why did USAPL switch from Wilks to DOTS?
USAPL switched to address the systematic bias in Wilks that disadvantaged lighter weight classes in Best Lifter competitions. After evaluating alternatives, USAPL adopted DOTS in 2019 as the most balanced available option for raw powerlifting comparisons.
Does my training change based on which scoring system my federation uses?
No. The scoring system affects how your competition performance is evaluated, not how you train. You train to increase your squat, bench, and deadlift. The coefficient system determines how those numbers translate into a comparative score after the fact.
What does a Wilks score of 300 mean?
A Wilks score of 300 falls in the Novice-to-Intermediate range based on historical benchmarks. It represents a meaningful competitive total but is not yet at advanced or elite levels. For context, sub-300 Wilks scores represent beginner-level competition totals for most weight classes.
