DOTS (Dynamic Objective Total Score) is the International Powerlifting Federation's preferred formula for comparing totals across bodyweight classes. It replaced the Wilks score as the IPF's official metric in 2019.
Formula
DOTS score = Total (kg) × 500 ÷ (a + b·BW + c·BW2 + d·BW3 + e·BW4)
Male coefficients: a = −307.75076, b = 24.0900756, c = −0.1918759221, d = 0.0007391293, e = −0.000001093.
Female coefficients: a = −57.96288, b = 13.6175032, c = −0.1126655495, d = 0.0005158568, e = −0.0000010706.
How it works
The DOTS formula uses a fourth-degree bodyweight polynomial (one degree lower than Wilks) with revised coefficients to produce a bodyweight-adjusted strength score, multiplying the total by 500 divided by the polynomial result.
DOTS was developed to address perceived inconsistencies in the Wilks formula at extreme bodyweights and is now widely used alongside it for ranking purposes. Results are most comparable within the bodyweight range used to fit the coefficients (roughly 40–210 kg).
Worked example
Worked example
- Inputs: total = 500 kg, bodyweight = 83 kg, sex = male.
- Evaluate the male fourth-degree polynomial at BW = 83.
- denom ≈ −307.75 + 24.09×83 + (−0.19188)×832 + 0.0007391×833 + (−0.000001093)×834 ≈ 740.65.
- DOTS = 500 × 500 ÷ 740.65 ≈ 337.54.
DOTS score = 337.54
Key terms
- DOTS
- A bodyweight-adjusted powerlifting score using a fourth-degree polynomial; designed as an updated alternative to the Wilks formula.
- Powerlifting total
- The sum of a lifter's best squat, bench press, and deadlift on the competition platform.
- Fourth-degree polynomial
- A curve with terms up to BW4 used to model the relationship between bodyweight and expected lifting performance.
- Bodyweight coefficient
- The polynomial value for a given bodyweight; used as the divisor so that heavier athletes are not inherently advantaged.
- Cross-class comparison
- Using a normalised score like DOTS to rank lifters of different bodyweights on a common scale, independent of weight category.
Frequently asked questions
- What is the difference between Wilks and DOTS?
- Both normalise powerlifting totals for bodyweight, but DOTS uses a 4th-degree polynomial while Wilks uses a 5th-degree polynomial. DOTS tends to favour lighter and heavier lifters slightly more than Wilks.
- What is a competitive DOTS score?
- National-level competitors typically score 350–420 DOTS. World-class lifters score 450+. Beginners should aim for 200+ as a first milestone.
