Powerlifting scoring formulas let you compare your performance across body weights, age groups, and even different eras of the sport. Understanding Wilks, DOTS, IPF GL, and McCulloch helps you set meaningful goals, track progress over time, and understand how your performance stacks up at any level of competition.
Wilks 2020 — The Updated Standard
The original Wilks formula was developed by Robert Wilks in the 1990s using competition data from the era. The updated 2020 formula was recalibrated using modern competition results from thousands of meets, improving fairness particularly at the extremes of the weight class spectrum — super-heavyweights had been systematically over-rewarded under the original equation. The core structure remains the same: your competition total (squat + bench + deadlift in kg) is multiplied by a polynomial coefficient that varies continuously with body mass rather than stepping at class boundaries. Male and female coefficients are separate equations. Many federations worldwide continue to use Wilks as their primary scoring system, and it remains the most widely recognized formula for informal comparisons among lifters online. When people say someone is a "350 Wilks lifter," they are using this formula — making it the common language of the sport regardless of which formula your federation officially uses.
DOTS — A Community-Driven Alternative
The DOTS score (Difficulty Over Total Score) was developed in 2019 as a grassroots alternative to address perceived inequities in the Wilks formula. It uses a 4th-degree polynomial formula fitted to a large dataset of modern competition results. Proponents argue DOTS produces more equitable comparisons across the full weight class range, particularly for the lighter and heavier classes where Wilks has historically produced less stable relative rankings. DOTS is popular in online lifting communities and smaller federations seeking an alternative to both Wilks and the IPF's official system. It tends to produce scores numerically similar to Wilks for most lifters in the middle weight classes, but diverges meaningfully for lighter women and heavier men. For most practical purposes — goal setting, tracking progress, and community comparisons — DOTS and Wilks will give you the same relative ranking against your peers. The formula is publicly documented, making it easy to reproduce and verify independently.
IPF GL Points — The Official IPF System
Unlike Wilks and DOTS, which apply a single coefficient to the competition total, IPF GL Points use per-lift exponential curves for squat, bench press, and deadlift independently. This fundamental structural difference means two lifters with identical totals but different S/B/D distributions receive different GL scores — a lifter who dominates on squat and deadlift but has a relatively weak bench will be penalized compared to a more balanced competitor with the same total. The IPF introduced GL Points in 2019 to replace the old Wilks system across all IPF-affiliated competitions. The per-lift approach was designed to reward balanced lifting and remove the incentive to concentrate training exclusively on the heaviest lifts. The IPF updates the GL coefficients periodically as the population of world-class competition data grows, ensuring the formula reflects current performance standards rather than historical ones. GL scoring is now the official basis for all IPF world championships and records.
McCulloch — Age-Adjusted Fairness
The McCulloch system multiplies a lifter's standard Wilks score by an age coefficient to account for physiological differences at the extremes of the age spectrum. Lifters aged 23–40 receive a 1.0 multiplier — no adjustment. Junior lifters under 23 receive increasing coefficients as they get younger, reaching 1.23 at age 14, reflecting that young lifters are still developing their neuromuscular systems and hormonal profiles relative to prime-age adults. Peak human strength typically occurs between ages 26 and 35, which is why this window carries no adjustment. Masters lifters over 40 receive progressively larger multipliers, starting at 1.02 at age 41 and reaching 2.55 at age 90. These adjustments allow fair best-lifter comparisons in masters divisions where a 60-year-old and a 35-year-old might otherwise compete on unequal terms. McCulloch scores are not used in open divisions — they are specifically for age-group competition and masters award calculations at federations that adopt the system. The adjustment formula is widely accepted in the masters powerlifting community.
