TL;DR
- DOTS 344.3, Wilks2 408.8, IPF GL 70.6 for an 83 kg male raw lifter with a 510 kg total. Three scoring systems on three different scales.
- One level once the scales are lined up. Wilks2 runs about 19% above DOTS and IPF GL about a fifth of it; on the DOTS scale all three read "Novice" for this lifter.
- Use DOTS as the default. Federations have largely standardized on DOTS for cross-bodyweight ranking; Wilks is legacy; GL is IPF-specific.
A 510 kg raw total at 83 kg bodyweight is a real intermediate-level number for a male powerlifter. The three scoring systems print very different numbers for it, but most of that is scale, not verdict: line the scales up and the differences shrink to a few points.
The scenario
Male lifter, 83 kg bodyweight (83 kg IPF class), raw (no knee wraps, no equipped suit), 510 kg total across the three lifts. Wants the DOTS, Wilks, and IPF GL score to know where the total ranks against the population and which system to use to track future progress.
What the calculator returns
Running the inputs through the DOTS / Wilks / GL Combined Calculator:
# dots-wilks-gl-combined-calculator (computed live from /engines/dots-wilks-gl-combined-calculator.js)
Engine input
sex = male
bodyweight_kg = 83
total_kg = 510
equipped = false
Engine output
dots.score = 344.2945615837787
dots.classification = Novice
wilks.score = 408.8378425600288
wilks.classification = Novice
gl.score = 70.59755712562882
gl.classification = Novice
bestSystem = GL
bodyweightKg = 83
totalKg = 510
bwRatio = 6.144578313253012Three systems, three numbers. The engine reports IPF GL as the lifter's "best system" (the one that rates the total highest once all three are on the DOTS scale), but the margin is a few points and the ranking is a curiosity rather than a recommendation. All three classify the total as Novice on the engine's bands.
Reading the numbers
Each system is a polynomial mapping from (bodyweight, total) → score, fitted to a competition dataset of a specific era[1][2]. Different cohorts produce different polynomial coefficients and different shapes of the bodyweight curve.
System Year Cohort Anchor
─────────────────────────────────────────────────────────────────
Wilks 1994 500 ÷ quintic in bodyweight
Wilks2 2020 600 ÷ quintic (new coefficients)
DOTS 2019 500 ÷ quartic in bodyweight
IPF GL 2020 100 ÷ (A − B·e^(−C·bodyweight))
For 83 kg male / 510 kg total:
DOTS bodyweight coefficient ≈ 0.6751
510 × 0.6751 ≈ 344.3
Wilks2 coefficient ≈ 0.8016
510 × 0.8016 ≈ 408.8
IPF GL (raw): 510 × 100 ÷ (1199.73 − 1025.18·e^(−0.00921·83))
≈ 70.6Wilks2 reads 64 points above DOTS almost entirely because of its 600-point numerator: divided by the engine's men's ratio of 1.186 it is 344.7, within half a point of DOTS. IPF GL divided by its ratio of 0.202 is 349.5, five points above. Those residual gaps are the real difference: how kindly each curve treats an 83 kg body.
Where the bands disagree
The classification bands in each system are based on different population percentiles.
DOTS bands (engine, men):
Beginner 0 – 300
Novice 300 – 400
Intermediate 400 – 500
Advanced 500 – 600
Elite 600+
Wilks2 bands = DOTS bands × 1.186:
Novice from 356, Intermediate 474, Advanced 593, Elite 712
IPF GL bands = DOTS bands × 0.202:
Novice from 60.6, Intermediate 80.8, Advanced 101, Elite 121A 344.3 DOTS, a 408.8 Wilks2 and a 70.6 GL all sit in the Novice band. The engine's bands are a rough guide, not federation standards; for a competitive lifter the practical implication is to choose a single system and stick with it across all training cycles to track progress consistently.
Why DOTS is the current default
Three reasons DOTS displaced Wilks in most US and European federations after 2019:
- Cohort recency. Wilks's 1994 dataset reflects pre-2000 raw competition. Modern raw lifting has produced larger totals per bodyweight class as training methods and nutrition have improved; the Wilks polynomial under-rewards modern totals at middle bodyweights.
- Extreme-class bias. Wilks rewarded 56 kg and 120+ kg lifters disproportionately. Top-ranked Wilks lifters historically clustered at the extreme classes by design. DOTS reduces but does not eliminate this bias.
- International alignment. The IPF moved to GL in 2020; non-IPF federations adopted DOTS as a parallel modern alternative. Wilks remains available in legacy database queries but is not the default ranking metric.
Equipped vs raw scaling
The engine input flagged this lifter as raw (no equipment). Equipped lifting (knee wraps, squat suit, bench shirt, single-ply or multi-ply gear) generally adds 10 to 25% to the total at the same bodyweight. An equipped 83 kg lifter totalling 625 kg would score DOTS ~422 and Wilks2 ~501: neither formula knows about equipment, so both read the higher total against the same bodyweight curve. IPF GL's equipped coefficients score the same 625 kg at ~72, close to the raw lifter's 70.6, which is the point of having them.
Most modern federations now run raw and equipped as separate categories with separate rankings, so the DOTS comparison of an equipped to a raw total is non-physiological. The engine returns the math; the federation context decides whether the comparison is meaningful.
Cross-checking against strength standards
The 510 kg total breaks down roughly as squat 185 + bench 115 + deadlift 210 for a typical 83 kg male. The Strength Standards Calculator can convert each individual lift into a population percentile. For this lifter, the squat sits at the Intermediate/Advanced boundary, the bench at Intermediate, the deadlift at Advanced/Elite — confirming that the total ranks at the Novice/Intermediate boundary because the bench is the weak link relative to the other two.

FAQ
What are DOTS, Wilks, and IPF GL scores for an 83 kg male with a 510 kg raw total? DOTS 344.3, Wilks2 408.8 and IPF GL 70.6. Put on one scale, all three land in the engine's Novice band; IPF GL rates the total marginally highest. DOTS is the common standard for cross-bodyweight comparison outside the IPF.
Why did DOTS replace Wilks in most federations? Wilks was refitted on a 1980s cohort and over-rewarded the lightest and heaviest weight classes. DOTS uses an updated polynomial fit on modern competition data; it under-rewards the extremes less and tracks middle-weight scores more linearly.
What does IPF GL measure differently? IPF GL is the points system used by the International Powerlifting Federation. It uses an exponential bodyweight curve instead of a polynomial, with separate raw and equipped coefficients, and its scores run at about a fifth of DOTS; the strongest lifters score above 100.
