DOTS score calculator.

What DOTS measures, and why the IPF switched from Wilks.

DOTS works the same way Wilks does at a high level: it multiplies your powerlifting total by a bodyweight-adjusted coefficient to produce a single number you can compare across weight classes. The difference is in the polynomial used to compute that coefficient.

Tim Konertz ran a detailed analysis of IPF competition data collected since the 1990s and found that the original Wilks curve had drifted significantly from reality. Modern raw lifting has changed. Equipment has changed. The athlete pool at the extremes of the bodyweight range has grown. The Wilks formula, which was fit to older and less representative data, was systematically over-rewarding very light lifters and under-rewarding super-heavyweights. The IPF adopted DOTS in January 2020 specifically to fix that problem.

How to read your DOTS number.

300 DOTS puts you in the Intermediate band. If you're there, you've built a real total and you understand how to compete. 400 DOTS (Advanced) is competitive at a regional meet in most weight classes. 500 DOTS (Elite) is national-class. Above 550 is approaching world-class for most categories.

The number is most useful as a trend metric. A 10-point swing week to week is noise from bodyweight variance and day-to-day performance variation. A 20-30 point gain across a full training cycle is a real result. If your DOTS holds steady while your bodyweight goes up, your relative strength is stalling.

DOTS vs Wilks vs Wilks 2.

DOTS is the current IPF standard. If you compete in the IPF or an IPF-affiliated federation (USAPL, British Powerlifting, and most major national federations that run IPF-rules events), your official meet score is DOTS. If you're tracking against an OpenPowerlifting profile or comparing to current IPF rankings, DOTS is the number that matters.

Wilks 2 is a separate update published in 2020 that revised the original Wilks coefficients using a larger dataset. It was not adopted by the IPF. Wilks 2 adoption outside that context is mixed, and most competitive lifters don't encounter it.

If you're comparing to gym records from before 2020, or against an older lifter's career numbers, use Wilks. That's what most informal records are built on. Check the Wilks calculator when you need the original formula.

The IPF also publishes GL points, its Goodlift score, and the IPF GL points calculator runs that formula.

What changed at the extremes.

The Wilks curve flattened out at very low and very high bodyweights, which meant lifters under 60 kg were consistently scoring higher than their actual relative strength output warranted, and lifters over 130 kg needed disproportionately large totals to compete with mid-weight lifters on the scoreboard.

DOTS smooths the curve at both ends by fitting to a more current and complete dataset. The trade-off is that lifters in the middle of the range, roughly 70-100 kg, see slightly different scores from Wilks, sometimes higher and sometimes lower depending on exact bodyweight. Neither formula is "right" in an absolute sense. DOTS is better calibrated to current competition data.

When DOTS isn't the right comparison.

Non-IPF federations. If your federation uses Wilks, comparing your DOTS to someone else's Wilks tells you nothing. Check which formula your fed actually uses before citing a score in a competition context.

Raw vs. equipped. DOTS doesn't distinguish between raw and equipped lifters. The federation handles that separation through equipment divisions. A 500 DOTS in single-ply is a very different achievement from a 500 DOTS raw, but the formula doesn't know and doesn't care.

Beginners with one strong lift and two weak ones. DOTS uses the S+B+D total. If your squat is strong but your bench and deadlift are undeveloped, your DOTS will understate your squat ability and overstate how balanced your training is. For beginners, tracking each lift's estimated max separately tells you more than the total score does.
