Each body keeps its own athlete list. GripCentral puts the same name from different bodies on one page, body by body, and never combines their numbers.

How records work
Records are set under a sanctioning body's rules — set, judging, and equipment all matter. A lift in your garage counts for you; a lift on the platform counts for the books. Each entry here is owned by the body that published it, shown by its badge and footnote.
Sanctioning bodies →Chasing a mark?
Records are set at sanctioned contests. Once a meet's results are posted to the owning body's database, new marks show up here at the next sync. Spot an error? Let us know.
