How DOTS works

One number for every bodyweight.

DOTS divides your total by a curve fitted to bodyweight, then scales it so that a strong total lands near 500. A 60 kg lifter and a 120 kg lifter can sit on the same ranking list, which is why many federations use it for best-lifter awards.

The formula is total × 500 ÷ (a + b·x + c·x² + d·x³ + e·x⁴), where x is bodyweight in kilograms and the five coefficients differ for men and women. It is fitted for 40–210 kg, so this calculator stops outside that range rather than guessing.

DOTS, Wilks 2020 and IPF GL

Wilks 2020 uses a fifth-degree curve and a larger scale. IPF GL is the IPF's own formula, with separate constants for classic and equipped lifting and for bench-only meets. Each federation picks one, so check which your meet uses before you compare.

FAQ

DOTS questions lifters ask

What is a good DOTS score?
It depends on your federation, sex and how long you have trained. A useful way to read it is against your own history: the milestone list above shows the total you need for the next 25, 50 and 75 points at your bodyweight.
Does DOTS use kilograms or pounds?
The formula runs in kilograms. Switch the units to pounds and the calculator converts before scoring, so the score is the same either way.
Can I use DOTS for a bench-only meet?
DOTS is built for the full total. For bench-only, IPF GL has its own bench constants: set Event to “Bench only” and read the IPF GL score.
Why do DOTS and Wilks give different numbers?
They use different curves and a different scale (500 vs 600 at the top end). Rankings between lifters mostly agree, but the numbers are not interchangeable.
