Hong Life CalculatorsUnderstanding the DOTS score calculator — concept and principle
DOTS (Dynamic Objective Team Scoring) is a powerlifting score that compares lifters of different bodyweights. It multiplies your total by a coefficient based on bodyweight and sex, and it has been adopted by many federations as a replacement for Wilks for best-lifter awards and team scoring.
How it is calculated
- Denominator = a + b·x + c·x² + d·x³ + e·x⁴, where x is bodyweight in kg
- Coefficient = 500 ÷ denominator
- DOTS score = total (kg) × 500 ÷ denominator
Men: a = −307.75076, b = 24.0900756, c = −0.1918759221, d = 0.0007391293, e = −0.000001093. Women: a = −57.96288, b = 13.6175032, c = −0.1126655495, d = 0.0005158568, e = −0.0000010706. Bodyweight is limited to 40–210 kg for men and 40–150 kg for women; values outside are treated as the nearest limit.
The principle
Like Wilks, DOTS starts from the fact that strength grows more slowly than bodyweight. Tim Konertz fitted a fourth-degree polynomial to recent competition results, aiming for a curve that treats light, middle and heavy lifters more evenly than Wilks. The clamped bodyweight range prevents the polynomial from behaving oddly at the extremes, where it would otherwise give unrealistic coefficients. The constant 500 keeps scores on a scale similar to Wilks.
Worked example
- Inputs: male, bodyweight 83 kg, total 600 kg; 83 kg is inside the 40–210 kg range.
- Terms: −307.75 + 1,999.48 − 1,321.83 + 422.62 − 51.87 = 740.64.
- Coefficient = 500 ÷ 740.64 = 0.6751, shown as 0.68.
- DOTS = 600 × 500 ÷ 740.64 = 405.05.
| Total lifted (kg) | DOTS score |
|---|---|
| 150 | 101.26 |
| 300 | 202.53 |
| 450 | 303.79 |
| 600 | 405.05 |
| 750 | 506.32 |
| 900 | 607.58 |
| 1,200 | 810.1 |
How to read the result
Higher is better. DOTS values are of a similar size to Wilks, though not identical: the same 83 kg, 600 kg lifter scores 405.05 DOTS and 400.5 Wilks. Roughly, 300 reflects a well-trained amateur, 400 a strong competitive lifter and 500 or more world-class performance. Use the score to compare your lifts over time, especially across a change of weight class, or to compare with lifters in other classes in the same category.
Common mistakes
- Using pounds instead of kilograms.
- Comparing DOTS scores with Wilks or IPF GL scores as if they were the same scale.
- Comparing raw (unequipped) totals with equipped totals.
Frequently asked questions
Is DOTS better than Wilks?
It was built from more recent results and aims to be more balanced across weight classes, which is why many federations adopted it, but every formula has some bias.
Why is bodyweight capped at 210 kg for men?
Beyond the fitted range the polynomial becomes unreliable, so DOTS uses the boundary value instead.
Can I compare men's and women's DOTS scores?
The formula uses separate constants for each sex, and direct comparison is not intended.
