About DOTS:
DOTS (Deviation from Optimal Total Strength) is a coefficient-based formula that normalizes powerlifting totals across different bodyweights, allowing fair comparison between lifters. Higher scores indicate greater relative strength.
DOTS Range
250-300
First 6-12 months of training, learning proper form
DOTS Range
350-400
1-3 years training, top 20% of lifters
DOTS Range
400-450
3-5+ years training, top 5% of lifters
DOTS Range
450-500
5-10+ years training, top 1% of lifters
DOTS Range
500+
Elite genetics + optimal training, top 0.1%
Female adjustments
-50 points
Women's benchmarks ~50 points lower per level
For 80kg male with 430kg total (150kg squat, 100kg bench, 180kg deadlift):

The DOTS (Deviation from Optimal Total Strength) calculator uses a sophisticated polynomial formula adopted by the International Powerlifting Federation (IPF) in 2019. This formula calculates a coefficient based on your bodyweight, then multiplies it by your powerlifting total to produce a normalized score that allows fair comparison across all weight classes.
DOTS Score = Total (kg) × DOTS CoefficientDOTS Coefficient = 500 / DenominatorDenominator = a×BW⁴ + b×BW³ + c×BW² + d×BW + eWhere BW is bodyweight in kilograms and a, b, c, d, e are gender-specific polynomial coefficients. Male coefficients: a=-0.0000010930, b=0.0007391293, c=-0.1918759221, d=24.0900756, e=-307.75076. Female coefficients differ to account for physiological differences in strength-to-weight ratios.
DOTS was developed to address limitations in the Wilks formula, which had been the standard since 1994. The Wilks formula became less accurate for very light (<52kg) and very heavy (>120kg) lifters. DOTS uses updated data from thousands of modern powerlifting competitions and provides better statistical fit across all bodyweight ranges.
