DOTS vs IPF GL: Choose the Right Score to Compare Powerlifters

Published 24 October 2026 · 6 min read

A bigger powerlifting total doesn’t always mean a stronger performance relative to bodyweight. A 700-kilogram total and a 500-kilogram total can’t be compared fairly by looking at the numbers alone.

DOTS and IPF GL are scoring systems that help compare lifters at different bodyweights. They use different formulas, so the same meet result can earn different scores. Knowing what each score measures helps you pick the right one for a meet ranking, training log, or cross-federation comparison. Here’s how DOTS and IPF GL work, where they differ, and how to avoid misleading comparisons.

DOTS vs IPF GL: What the scores measure

Both systems turn a powerlifting total into a score that adjusts for bodyweight and sex. IPF GL also accounts for lifting category, such as classic or equipped. A score helps compare performances, but it doesn’t replace the official total or placing.

How DOTS turns a total into a score

DOTS uses a coefficient-based formula. It combines a lifter’s total with their bodyweight and sex to calculate a score. The DOTS calculator from Strength Level can help you check a result without relying on old or copied coefficients.

How IPF GL accounts for competition categories

IPF GL uses its own formula and category-specific coefficients. Select the correct sex and lifting type, including classic or equipped, in the official Goodlift IPF GL calculator. The IPF’s formula page says IPF GL replaced the earlier IPF formula for sanctioned events from May 1, 2020.

What the scores can—and cannot—tell you

A higher score means a higher result under that formula’s bodyweight adjustment. It doesn’t tell you how clean a lift looked, how long someone has trained, or how hard the attempt felt. Use the meet total and lift results to understand the performance itself.

Why DOTS vs IPF GL scores can differ

The two scores aren’t interchangeable. Each formula applies a different mathematical model, and IPF GL also distinguishes between lifting categories. As a result, one meet total can receive two different scores without either calculation being wrong.

Different formulas produce different results

DOTS and IPF GL use different equations to adjust a total for bodyweight. Neither score is a simple percentage of the total, and one can’t be converted to the other by adding or subtracting a fixed amount. Always name the formula when you share a score.

Bodyweight and sex affect the calculation

Both formulas use the lifter’s bodyweight and sex-related inputs or category settings. A small input error can change the result, especially if you enter pounds where the calculator expects kilograms. Check the units and category before you compare scores.

Classic and equipped lifting may be treated differently

IPF GL offers separate settings for classic and equipped lifting. Choose the setting that matches the event, since a score from the wrong category won’t answer the comparison you intended. When comparing results across lifting styles, state the difference rather than treating the scores as direct equivalents.

Which scoring system should you use?

There isn’t one best score for every purpose. The right choice depends on the federation, meet rules, and lifters you want to compare. Use the formula that fits the setting, then keep it consistent.

Use IPF GL for comparisons within IPF contexts

IPF GL is the natural choice when you’re reviewing IPF results or comparing lifters under the relevant IPF categories. It’s also used at IPF-sanctioned events, according to the federation’s formula page. Check the meet’s rules before using a score to explain awards or rankings.

Use DOTS for broader performance comparisons

DOTS is a common option for comparing lifters across bodyweights outside a specific IPF setting. It works best when the meet, ranking site, or group you’re using also relies on DOTS. If other lifters are listed by IPF GL, don’t compare those numbers directly with your DOTS score.

Match the formula to the question

For a best-lifter ranking at one meet, follow the meet’s scoring rules. To track your own progress, use the same formula each time. When comparing results from different federations, pick one score and calculate every lifter’s result with it.

How to calculate and compare scores accurately

A fair comparison starts with accurate meet data. Use official results and a calculator with the right formula and settings. If the score is for a ranking or report, record which formula produced it.

Enter the correct total, bodyweight, and category

Use the total recorded at the meet, not a gym estimate or projected total. Enter the weigh-in bodyweight and the correct sex, units, and lifting category. A wrong unit or division can distort the score.

Compare like with like

Calculate every result with the same formula and relevant category settings. A DOTS score of 350 and an IPF GL score of 350 don’t mean the lifters performed equally under one shared scale. Label each score as DOTS or IPF GL wherever you publish it.

Track scores consistently over time

Keep the formula fixed when you track your progress across meets. If you switch from DOTS to IPF GL, recalculate your past results with IPF GL before comparing the numbers. For published rankings, cite the calculator and formula version; Goodlift’s calculator and the IPF formula page are useful places to check IPF GL details.

Common mistakes that lead to misleading comparisons

Score comparisons can look clear while hiding differences in formula or competition rules. Check the settings before drawing conclusions from a leaderboard or online post. A few simple checks can prevent an unfair ranking.

Treating DOTS and IPF GL as equivalent

The scores use different formulas, so matching numbers don’t guarantee matching performance comparisons. Don’t rank one lifter’s DOTS against another lifter’s IPF GL. Recalculate both results using the same system.

Comparing different lifting categories without context

Classic and equipped results come from different lifting conditions. Even when a scoring tool provides category-specific points, that doesn’t make the underlying performances identical. State the lifting style and rules when you compare results.

Assuming the highest score settles every debate

A formula-based score answers a limited question: how a total compares after the formula’s adjustments. It doesn’t measure every part of a performance or settle which lift was most impressive. Use the score as one useful comparison, not a final verdict.

Choose the score that fits your comparison

Use IPF GL for comparisons within the relevant IPF setting, and DOTS when a meet or community uses it. Never treat the two numbers as if they share one scale. Accurate inputs and a consistent formula make any comparison clearer.

Key takeaways for lifters and meet organizers

Identify the scoring formula before reading or sharing a score. Confirm the correct bodyweight, units, sex, and lifting category, then check the result against official meet data. Label scores clearly so readers know what they’re comparing.

Sources to check before publishing or ranking results

For IPF GL, consult current IPF information and the Goodlift calculator. For DOTS, use a published formula reference or a trusted calculator that identifies its inputs. When reporting rankings, note the formula and calculator used.

Conclusion

DOTS and IPF GL both adjust a powerlifting total to help compare lifters across bodyweights, but their formulas differ. IPF GL also separates relevant lifting categories, so choosing the right settings matters. Pick the score that fits your meet or comparison, use it consistently, and label it every time.
