How to read these figures

• Sinclair score. The total scaled for bodyweight with the IWF's 2025 to 2028 coefficients, so lifters from different classes sit on one scale. Women and men have separate formulas.
• Place in its class. Where the best total stands among every lifter with a total in that class on this site, on the IWF class list in force at the time.
• Attempts made. The share of all snatch or clean and jerk attempts the lifter made. At senior World Championships and Olympic Games since 1998, lifters make 58% of snatches and 56% of clean and jerks.
• Snatch as a share of clean and jerk. The snatch divided by the clean and jerk at the best total. It describes the shape of a lifter, not strength, so it is not in bold; eight in ten women lifting in national federation meets sit between 70% and 85%.
• World records held now. Records on the IWF class list in force since 1 August 2026. A record set in a class that list retired does not carry over, so a past record holder can show none.

Katherine Vibert and Rim Jong-sim never lifted in the same class at the same competition. The results here run from 2018 to 2024 for Katherine Vibert and 2009 to 2019 for Rim Jong-sim, so the side by side figures and the chart are the comparison.

The Sinclair score at each competition: the total scaled for bodyweight, so lifters from different classes sit on one scale. Competitions that ended without a total or a bodyweight have no point.
