What is DOTS score?
The DOTS score is a single bodyweight-adjusted number that lets you rank powerlifters against each other regardless of weight class, using a formula built specifically from current, drug-tested Raw lifting data. It answers the same question as the older Wilks score — 'who had the best total relative to their bodyweight?' — but with coefficients recalculated from modern competition results instead of the equipped-lifting data Wilks was originally built on.
How it works
DOTS works by running your bodyweight through a fourth-degree polynomial to produce a denominator, then dividing 500 by that denominator and multiplying the result by your total (in kg). Because the underlying dataset is drug-tested Raw results rather than 1990s equipped totals, DOTS tends to track more accurately with what a modern natural, unequipped lifter can actually total at a given bodyweight — one of the main complaints that pushed federations away from Wilks in the first place.
The formula
DOTS score = total (kg) × 500 / (a·BW⁴ + b·BW³ + c·BW² + d·BW + e)
BW is bodyweight in kg; a-e are sex-specific constants published by the formula's creator. As with Wilks, no one calculates this by hand — meet software and online calculators do the polynomial math instantly from your bodyweight, sex and total.
How to apply it
- Rank a meet regardless of weight class: Multiply each lifter's total by their DOTS coefficient and the highest score wins 'Best Lifter,' the same job Wilks used to do.
- Compare across federations: USPA and WRPF meets typically post DOTS on the scoreboard alongside kg totals, so lifters from different weight classes can be ranked on one leaderboard.
- Benchmark your own strength standard: A DOTS score in the mid-300s to 400s is commonly used as a rough 'intermediate to advanced Raw lifter' benchmark, independent of bodyweight.
- Track progress after a weight-class change: If you cut or bulk between meets, comparing DOTS scores (not just kg totals) shows whether you actually got relatively stronger.
Worked example
Say two Raw lifters compete in the same USPA meet: a 67.5 kg lifter totals 500 kg and an 83 kg lifter totals 620 kg. Here's how DOTS compares them.
| Lifter | Bodyweight | Total | DOTS coefficient (approx.) | DOTS score |
|---|---|---|---|---|
| A | 67.5 kg | 500 kg | 0.72 | 360.0 |
| B | 83 kg | 620 kg | 0.615 | 381.3 |
Lifter B's DOTS score edges out Lifter A here because 620 kg is a large enough total to outweigh the extra bodyweight in the formula. Coefficients shown are approximate for illustration — use an official DOTS calculator for real scoring.
DOTS score vs Wilks score
| DOTS | Wilks (2020) | |
|---|---|---|
| Created | Tim Konertz, 2019 | Robert Wilks, 1995 (revised 2020) |
| Built from | Drug-tested Raw competition data | Historical Single-ply (equipped) data |
| Numerator | 500 | 600 (post-2020 revision) |
| Primary users | USPA, WRPF, most modern Raw federations | Federations still on the legacy formula; historical comparisons |
IPF and its affiliates (like USAPL) use neither — they score with their own IPF GL Points formula.
By goal
- USPA/WRPF competitors: Check your federation's rulebook — most modern Raw federations default to DOTS for Best Lifter awards, so that's the number worth tracking meet to meet.
- Lifters comparing historical records: Older meet results are usually posted in Wilks, not DOTS, so compare like-for-like when looking at all-time rankings.
Common misconceptions
- "DOTS and Wilks always rank lifters the same way." Because the two formulas are built from different datasets and different polynomials, they can rank the same pair of totals in a different order, especially at the extreme ends of the bodyweight range.
- "DOTS replaced Wilks everywhere." USPA and WRPF adopted DOTS, but IPF-affiliated federations (including USAPL) use IPF GL Points instead, and some smaller federations still default to Wilks.
- "A DOTS score close to 500 is normal for a serious lifter." A DOTS score near 500 is elite/world-class territory — most competitive intermediate Raw lifters sit in the 300s to low 400s.

DOTS score FAQ
What is a good DOTS score?
A DOTS score in the 300s is a solid intermediate Raw lifter, the 400s is strong national-level competitive territory, and 450+ starts to reach elite/world-class, though this varies by federation and division.
Why was DOTS created if Wilks already existed?
Wilks was built from 1990s equipped-lifting data that critics said unfairly favored certain bodyweights; Tim Konertz built DOTS in 2019 from modern, drug-tested Raw results to better reflect how today's natural lifters actually total.
Does USAPL use DOTS?
No — USAPL, as an IPF affiliate, uses IPF GL Points for its official rankings and Best Lifter awards, not DOTS. DOTS is the primary formula for federations like USPA and WRPF.
How do I calculate my DOTS score?
Enter your bodyweight, sex and total into a free online DOTS calculator — the fourth-degree polynomial math isn't practical to do by hand, so lifters and meet directors use software instead.
Is DOTS more accurate than Wilks?
Most coaches consider DOTS a fairer reflection of modern Raw strength standards because it's built from drug-tested Raw data, but 'more accurate' depends on which population and lifting style you're comparing.
