A modern bodyweight-adjusted strength score
DOTS (Dynamic Objective Team Scoring) is the coefficient many federations adopted to rank lifters across weight classes after concerns about the older Wilks curve. Like Wilks, it converts a raw total into a single comparable number — but it is fitted to a newer dataset and uses the same formula for everyone of a given sex, which makes it cleaner to apply.
How it works
The DOTS coefficient is built from a fourth-degree polynomial of bodyweight x in kilograms:
coefficient = 500 / (a·x⁴ + b·x³ + c·x² + d·x + e)
DOTS score = coefficient × total_in_kgThe five constants a through e are one set for men and another for women. A pound total is divided by 2.2046226218 to convert to kilograms before the formula runs, so the result is unit-independent.
Why DOTS was developed
The Wilks coefficient was the dominant bodyweight-adjustment formula for decades, but criticism accumulated around two patterns: it systematically under-rewarded lighter lifters (below about 65 kg) and over-rewarded very heavy lifters (above about 120 kg). This meant that all-time records and bodyweight-adjusted rankings clustered in certain weight classes in ways that did not reflect actual relative strength.
DOTS was developed by the 100% RAW Powerlifting Federation as a replacement. Its polynomial was fitted to actual competition data to produce a flatter curve across the full bodyweight range — a lifter at 55 kg and a lifter at 100 kg competing on equal terms should produce similar DOTS scores if their relative strength is comparable. It was subsequently adopted by several other federations, though IPF uses its own IPF GL (GL Points) formula.
DOTS vs other formulas
| Formula | Scale word | Notable feature |
|---|---|---|
| DOTS | None (raw number) | One polynomial for each sex; fitted to modern data |
| Wilks | None (raw number) | Older; tends to favour heavier lifters |
| IPF GL | GL Points | Separate formulas for raw and equipped, age-corrected |
| Schwartz/Malone | None | Older formula; rarely used in modern competition |
When comparing scores, always confirm everyone is using the same formula. Mixing DOTS and Wilks scores is a common error in informal comparisons.
Score benchmarks
These are rough reference points based on the broader competitive population:
| DOTS score | Level |
|---|---|
| Below 200 | Beginner |
| 200–300 | Intermediate |
| 300–400 | Advanced |
| 400–500 | Highly advanced |
| 500+ | Elite / competitive nationally |
These thresholds are approximate and vary by sex and federation. The distribution differs between men and women (same formula, different constants) and between raw and equipped lifting.
Worked example
A female lifter at 63 kg with a 350 kg total (for example, 130 squat, 80 bench, 140 deadlift):
- The women’s polynomial with x = 63 yields a coefficient near 1.07 (the exact value depends on the constants).
- DOTS score ≈ 1.07 × 350 ≈ 374–378 — strongly advanced, competitive at national level in most raw federations.
For comparison, a 90 kg male lifter with a 600 kg total would score roughly 400–420, placing him in a similar tier.
Enter your full competition total (squat + bench + deadlift), not a single lift. The tool converts pounds to kilograms automatically before applying the polynomial.
