The DOTS (Dynamic Objective Team Scoring) system is a revolutionary metric in the world of powerlifting. It allows athletes, coaches, and enthusiasts to evaluate lifting performances across diverse body weights and genders. This standardized system ensures a fair comparison of strength levels, irrespective of physical differences. In this blog, we will dive deep into how the DOTS system works, its formula, and why it has gained significant traction in the powerlifting community.
What is the DOTS Scoring System?
Powerlifting is a sport where lifters of varying body weights compete by lifting the maximum possible weight in three categories: squat, bench press, and deadlift. Comparing the performance of athletes with different body weights has always been a challenge. The DOTS system addresses this challenge by providing a scientifically grounded formula to normalize and test your performance scores.
How Does DOTS Work?
The DOTS score is calculated using the following formula:
DOTS Score=Total Weight Lifted×500a+b×x+c×x2+d×x3+e×x4text{DOTS Score} = frac{text{Total Weight Lifted} times 500}{a + b times x + c times x^2 + d times x^3 + e times x^4}DOTS Score=a+b×x+c×x2+d×x3+e×x4Total Weight Lifted×500
Here’s a breakdown of the formula:
- Total Weight Lifted: The sum of the athlete’s best squat, bench press, and deadlift attempts, measured in kilograms.
- x: The athlete’s body weight in kilograms.
- a, b, c, d, e: Coefficients tailored to each gender to ensure accuracy.
Coefficients for the DOTS Formula:
| Coefficient | Men | Women |
|---|---|---|
| a | -307.75076 | -57.96288 |
| b | 24.0900756 | 13.6175032 |
| c | -0.1918759221 | -0.1126655495 |
| d | 0.0007391293 | 0.0005158568 |
| e | -0.000001093 | -0.0000010706 |
These coefficients are derived from extensive statistical modeling, ensuring the formula captures the relationship between body weight and lifting performance effectively.
Example Calculation:
Let’s consider a male powerlifter who weighs 80 kg and lifts a total of 600 kg across the three lifts. Using the coefficients for men:
a=−307.75076, b=24.0900756, c=−0.1918759221, d=0.0007391293, e=−0.000001093a = -307.75076, b = 24.0900756, c = -0.1918759221, d = 0.0007391293, e = -0.000001093a=−307.75076, b=24.0900756, c=−0.1918759221, d=0.0007391293, e=−0.000001093
Step 1: Compute the denominator
Denominator=a+(b×x)+(c×x2)+(d×x3)+(e×x4)text{Denominator} = a + (b times x) + (c times x^2) + (d times x^3) + (e times x^4)Denominator=a+(b×x)+(c×x2)+(d×x3)+(e×x4)
- b×x=24.0900756×80=1,927.206048b times x = 24.0900756 times 80 = 1,927.206048b×x=24.0900756×80=1,927.206048
- c×x2=−0.1918759221×802=−1,228.805901c times x^2 = -0.1918759221 times 80^2 = -1,228.805901c×x2=−0.1918759221×802=−1,228.805901

- e×x4=−0.000001093×804=−45.016576e times x^4 = -0.000001093 times 80^4 = -45.016576e×x4=−0.000001093×804=−45.016576
- Denominator=−307.75076+1,927.206048−1,228.805901+377.108301−45.016576=722.741112text{Denominator} = -307.75076 + 1,927.206048 – 1,228.805901 + 377.108301 – 45.016576 = 722.741112Denominator=−307.75076+1,927.206048−1,228.805901+377.108301−45.016576=722.741112
Step 2: Compute the DOTS Score
DOTS Score=600×500722.741112≈415.18text{DOTS Score} = frac{600 times 500}{722.741112} approx 415.18DOTS Score=722.741112600×500≈415.18
The result, 415.18, represents the athlete’s performance adjusted for body weight, allowing fair comparisons with others.
Why DOTS is Revolutionizing Powerlifting
- Fair Comparisons:
- DOTS provides an equitable way to compare lifters of different body weights and genders.
- It eliminates biases inherent in raw totals, which favor heavier lifters.
- Data-Driven Accuracy:
- The coefficients used in DOTS are based on modern statistical analyses, making it a reliable tool.
- Widespread Adoption:
- Major powerlifting organizations like USAPL and USPA have incorporated DOTS for competitions, replacing older metrics like Wilks.
How Does DOTS Compare to Wilks?
The Wilks formula was a popular scoring system in powerlifting for decades. However, it was based on outdated data, which sometimes led to discrepancies in scoring fairness. DOTS has emerged as a superior alternative by using contemporary data and refined coefficients, ensuring a more accurate reflection of strength performance.
