About DOTS Score Calculator

DOTS uses a fourth-order polynomial fitted to modern raw lifting data, correcting the weight-class bias critics found in Wilks. A 500 kg total at 90 kg scores about 320 DOTS. Because the two formulas use different fits, DOTS and Wilks scores are close but not interchangeable, and only one should be used within a ranking.

Formulas

DOTS coefficient

coeff = 500 / (a + bx + cx^2 + dx^3 + ex^4), x = body weight

DOTS score

score = total x coefficient

Worked example

With the default values below, DOTS Score Calculator returns DOTS Score of 323.30. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • This is an estimate from population-average equations, not a medical or diagnostic assessment. Individual results vary with genetics, training history and technique. Seek advice from a qualified coach or clinician before making significant changes to training.
  • This is an estimate for general information and not professional medical advice. See the full disclaimer for the limits that apply to this kind of calculator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why did DOTS appear?

It was fitted to raw (unequipped) lifting data, which had grown enormously since Wilks was derived from mostly equipped totals.

Which formula do federations use?

The IPF uses GL points, USAPL and many raw meets use DOTS, and Wilks persists informally. Check your federation's current rules.
