Frequently Asked Questions

• What is the DOTS score in powerlifting? ▼
  DOTS (named for the author's initials, Tim Konertz) is a powerlifting scoring formula published in 2020 as an alternative to the Wilks formula. Like Wilks, it normalizes a lifter's total (squat + bench + deadlift in kg) by a sex-specific coefficient based on bodyweight, producing a single score that allows comparison across weight classes. The DOTS formula uses a fourth-degree polynomial denominator: Score = Total × 500 / (a + b·BW + c·BW² + d·BW³ + e·BW⁴), with separate coefficients for male and female lifters. The coefficient 500 is chosen so that elite performances produce scores near 500, which aligns with intuitive benchmarking. DOTS was developed specifically to address calibration problems observed with Wilks at the extremes of the bodyweight range — particularly the tendency of Wilks to over-reward very light lifters relative to observed world-record distributions.
• Why was DOTS created if we already had Wilks? ▼
  The Wilks formula, originally published in 1994, was calibrated against performance data from that era. As powerlifting standards evolved over the subsequent 25 years — through improved training methodology, better equipment, more sophisticated periodization, and more rigorous drug testing in tested federations — the observed relationship between bodyweight and world-record totals shifted. Wilks became increasingly poorly calibrated, particularly at bodyweights below 60 kg (where it tended to give inflated scores) and above 110 kg (where it sometimes under-rewarded super-heavyweight performances). Tim Konertz analyzed the OpenPowerlifting database of modern world-record performances and fitted new polynomial coefficients to the 2020 data, producing DOTS. Additionally, the Wilks 2020 update was published at roughly the same time, creating a confusing situation where multiple competing systems exist. DOTS has been adopted by several federations and is the preferred formula on the OpenPowerlifting platform.
• How does DOTS compare to Wilks for lighter vs heavier lifters? ▼
  For lifters in the middle bodyweight range (approximately 70–90 kg for men, 55–72 kg for women), DOTS and Wilks produce similar scores — both formulas were calibrated to the same underlying athletic population and agree in the most heavily-competed weight classes. The divergence appears at the extremes. For very light lifters (men below 59 kg, women below 47 kg), Wilks tends to assign higher scores relative to DOTS, reflecting the fact that Wilks over-rewards lighter lifters based on older data where fewer elite performances existed at low body weights. For super-heavyweights (men above 120 kg), DOTS tends to assign higher scores relative to Wilks 1994, better reflecting modern super-heavyweight world-record performances. The practical implication is that cross-class comparisons can shift ranking when you switch formulas — a lifter who looks stronger on Wilks might appear weaker on DOTS or vice versa, depending on their weight class.
• Which scoring system do most federations use today? ▼
  The powerlifting scoring landscape in 2025 is fragmented. The IPF (International Powerlifting Federation) and its affiliates — including USAPL (USA), CPU (Canada), BP (Great Britain), and most European national federations — use IPF GL Points for official Best Lifter awards at sanctioned competitions. The WPC (World Powerlifting Council) and many unsanctioned or independent federations continue to use Wilks 1994. DOTS is used by the OpenPowerlifting analytical platform for cross-era comparisons and is growing in adoption among online powerlifting communities as a preferred analytical tool. Some newer federations (particularly in Europe) have adopted DOTS for their sanctioned competitions. The fragmentation means that a lifter's 'best scoring system' depends on their weight class and era of competition — serious competitive lifters routinely track all three scores. For most recreational lifters, any of the three systems serves equally well for tracking relative progress.
• Can I convert between Wilks, DOTS, and IPF Points? ▼
  There is no simple conversion factor between the three systems because each formula produces different shapes of coefficient curves across the bodyweight spectrum — they agree in the middle ranges and diverge at the extremes. The only rigorous conversion is to recalculate using each formula independently with the same inputs (total in kg and bodyweight in kg). All three formulas are deterministic given total and bodyweight, so this calculator (and the companion IPF Points calculator) can show all three values side by side for any performance. Rough equivalencies for competitive benchmarking: a Wilks 500 is approximately DOTS 495–510 for a mid-range male lifter; IPF Points 500 corresponds roughly to the same range. However, at extreme bodyweights these equivalencies can differ by 20–50 points. For cross-federation or cross-era comparisons, it is best to either use the formula adopted by the specific federation in question, or use DOTS as a common reference since it has the most modern calibration.
