In the world of powerlifting, athletes of all sizes and strengths compete to lift the heaviest weights possible across three main lifts: the squat, bench press, and deadlift. However, comparing performances directly can be unfair due to differences in body weights and genders. This is where the Dots Powerlifting Calculator comes into play. It’s a tool designed to level the playing field, allowing for fair comparisons across different categories by using a mathematical formula.
Purpose and Functionality
The Dots Calculator uses a formula to assign a score to a lifter based on their total lifted weight, body weight, and gender. This score makes it possible to compare the relative strength of lifters regardless of their size or gender. The formula takes into account the physiological differences between genders and the non-linear relationship between body weight and lifting capability. Essentially, it answers the question: “Given two lifters of different sizes, who is the stronger relative to their size?”
The Formula Explained
The core of the Dots Calculator is its formula, which adjusts a lifter’s total lifted weight for their body weight and gender. Here’s a simplified breakdown:
Inputs Needed:
- Total Lifted (
total_lifted): The combined weight of the lifter’s best squat, bench press, and deadlift in kilograms. - Body Weight (
body_weight): The lifter’s body weight in kilograms. - Gender: The lifter’s gender (male or female) to apply the correct coefficients in the formula.
The Calculation:
For Males and Females, the formula slightly varies due to different coefficients:
- X = (body_weight / 47.195)^(0.163)
- Dots Score = (total_lifted * 500) / (a + (b * X) + (c * X^2) + (d * X^3))
Where a, b, c, and d are gender-specific coefficients.
Coefficients:
- For Males: a = -216.0475144, b = 16.2606339, c = -0.002388645, d = -0.00113732
- For Females: a = 594.31747775582, b = -27.23842536447, c = 0.82112226871, d = -0.00930733913
Step-by-Step Example
Let’s calculate the Dots score for two hypothetical lifters:
- Lifter A (Male): Total lifted = 600kg, Body weight = 80kg
- Lifter B (Female): Total lifted = 450kg, Body weight = 60kg
By applying their respective data to the formula, we’d calculate each of their Dots scores, which then allows us to compare their performances objectively.
