DOTS, bodyweight and weight class: how to compare lifters fairly

A 200 kg squat means something very different at 60 kg bodyweight than at 120 kg. The lighter lifter is moving more than three times their own weight, a feat at the edge of human capability. The heavier lifter is strong, but the same number is a different story relative to their frame. Raw totals alone cannot compare them fairly.

This is the problem DOTS solves. It is a formula that takes a lifter is total and their bodyweight and returns a single score, calibrated so that an exceptional performance at any bodyweight lands in the same range. A featherweight and a heavyweight who are equally impressive for their size will sit close together on the DOTS scale, even though their raw totals are far apart.

It replaced the older Wilks formula in many federations because it fits modern lifting data more accurately across the full range of bodyweights, with fewer distortions at the very light and very heavy ends. In practice it is the fairest single number we have for ranking lifters of different sizes against each other.

That is why the Big Z leaderboard ranks on DOTS rather than raw total. It means a 63 kg athlete and a 120 kg athlete are competing on the same board, judged on how strong they are for who they are. Bodyweight is context, not a handicap, and DOTS is how we keep the comparison honest.
