DOTS Calculator

The DOTS score is the modern successor to the Wilks formula for comparing powerlifters across bodyweights and sexes. Introduced in 2019 and now the default for many federations, DOTS rebuilds the coefficient from updated data and a refined polynomial. If you want a single fair number that ranks a 56 kg lifter against a 140 kg lifter, DOTS is the current standard — and it fixes the specific weak spots Wilks was criticized for.

What DOTS Is

DOTS (sometimes written as the IPF GL or grouped with the newer relative-strength formulas) takes your total lifted and your bodyweight and returns a points score that already accounts for the non-linear way strength scales with mass. Like Wilks, a higher number means a stronger pound-for-pound performance. Unlike Wilks, it was calibrated on a more recent, broader pool of competition data.

How DOTS Differs From Wilks

DOTS is not just Wilks with new numbers — the underlying design changed in three meaningful ways:

• A newer polynomial: DOTS uses an updated fourth/fifth-order curve fitted to modern results, correcting the bias Wilks showed toward middle weight classes.
• One equation per sex, applied uniformly: DOTS uses a single continuous coefficient function across the entire bodyweight range for each sex, rather than treating the extremes as special cases. This is what makes it fairer at very light and very heavy bodyweights — the lifters Wilks served worst.
• Better tail behavior: Because the curve is smoother at the extremes, a 52 kg lifter and a 150 kg lifter are scored more equitably against the middle of the field.

In short: same goal as Wilks, but a more even playing field, especially if you're at the edges of the weight spectrum.

The Coefficient Idea

DOTS multiplies your total by a coefficient derived from a polynomial of bodyweight, with separate constants for men and women:

The structure looks similar to Wilks, but the constants and the fit are different — which is exactly why the two formulas give different scores for the same lifter, especially at the extremes. The calculator applies the official DOTS coefficients automatically.

Interpreting Your DOTS Score

The score bands deliberately mirror the Wilks ranges so lifters familiar with the old system can read DOTS intuitively, but a given lifter's DOTS and Wilks numbers will rarely match exactly — expect a few points of difference, larger at the bodyweight extremes.

Which Federations Use DOTS

• USAPL and many national bodies adopted DOTS as their primary ranking formula.
• Numerous raw / drug-tested federations and meet-scoring platforms now default to DOTS.
• The IPF uses its own related GL points formula for international rankings, while DOTS remains the widely used independent standard.
• Most modern online leaderboards and meet software report DOTS alongside or instead of Wilks.

If you're comparing your number to others, always confirm both performances use the same formula and the same equipment/tested division.

Note: The DOTS score is a comparison tool for informational use only. It reflects relative powerlifting strength, not overall health or athleticism. Consult a qualified coach before attempting maximal lifts.
