Formula Used
DOTS compares strength across body sizes by multiplying your total by a coefficient based on bodyweight. It uses a fourth-degree polynomial to create the coefficient.
x = bodyweight (kg), w = total lifted (kg)

Example Data Table
| Sex | Bodyweight (kg) | Total (kg) | DOTS (approx.) |
|---|---|---|---|

FAQs
1) What does a DOTS score measure?
It measures relative strength by adjusting your powerlifting total for bodyweight and sex. This helps compare lifters across different sizes using one score.
2) Do I need all three lifts to calculate?
No. You can enter squat, bench, and deadlift, or switch to total-only mode. The calculator converts everything to kilograms before scoring.
3) Should I use training numbers or meet numbers?
Meet totals are best for consistent comparisons. Training totals work too, but variations in depth, commands, and equipment can change results.
4) Does the score change if I use pounds?
The final score is the same. Pounds are converted to kilograms internally, so your DOTS score matches what you would get using kilograms directly.
5) Why is there a coefficient shown?
The coefficient is the bodyweight adjustment factor from the polynomial. DOTS score equals coefficient multiplied by your total lifted in kilograms.
6) Is DOTS used for equipped lifting?
Many people apply it to raw totals. Equipped lifting can inflate totals, so some events prefer other scoring methods. This tool still computes DOTS from any total you enter.
7) What is a “good” DOTS score?
It depends on federation and level. Roughly, scores around 300–400 are common among trained lifters, 400–500 are very strong, and 500+ is elite in many contexts.
8) Why do my results look unusual at very low or high bodyweights?
Scoring models are tuned to typical competition ranges. Extreme bodyweights can produce less intuitive coefficients. Use weigh-in bodyweight and double-check unit selection.
