DOTS and Wilks calculator

Both scores multiply the total (best squat + bench press + deadlift, in kilograms) by a coefficient that falls as body weight rises. Pound inputs are converted exactly (1 lb = 0.45359237 kg) first. The coefficients and body-weight limits are the ones OpenPowerlifting uses, and points are rounded to two decimals as it shows them.

DOTS (Dynamic Objective Team Scoring) was introduced by the German federation BVDK and written by Tim Konertz. The denominator is a fourth-degree polynomial in body weight x, in kilograms. Body weight outside 40 to 210 kg (men) or 40 to 150 kg (women) counts as the nearest end of that range.

DOTS = total × 500
       / (a·x⁴ + b·x³ + c·x² + d·x + e)

Men    a = −0.000001093
       b = 0.0007391293
       c = −0.1918759221
       d = 24.0900756
       e = −307.75076

Women  a = −0.0000010706
       b = 0.0005158568
       c = −0.1126655495
       d = 13.6175032
       e = −57.96288

Wilks is Robert Wilks’ original formula; the IPF has since moved to its own points. Its denominator is a fifth-degree polynomial. OpenPowerlifting holds body weight to 40 to 201.9 kg for men and 26.51 to 154.53 kg for women. That keeps clear of the polynomial’s asymptote at the heavy end and of very large coefficients at the light end.

Wilks = total × 500
        / (a + b·x + c·x² + d·x³
           + e·x⁴ + f·x⁵)

Men    a = −216.0475144
       b = 16.2606339
       c = −0.002388645
       d = −0.00113732
       e = 0.00000701863
       f = −0.00000001291

Women  a = 594.31747775582
       b = −27.23842536447
       c = 0.82112226871
       d = −0.00930733913
       e = 0.00004731582
       f = −0.00000009054

The scores are for comparing lifters, within a meet or across meets, not for grading one lifter. A score is only as comparable as the totals behind it: equipment, federation rules and drug testing all differ. Neither formula defines levels such as “beginner” or “elite”, so none are shown.
