Pyraminx · top 2.3% of 129,321 all-time · competing since December 2023 · 2023CAOJ03
Jingyi Cao (曹婧伊) has been competing for 3 years. Her best event is the Pyraminx: a personal-best single of 2.55, set at Shenyang Spring 2025, puts her in the top 2.3% of the 129,321 people who have ever been ranked in the event, and 277th in China. Until January 2011, no official Pyraminx solve in the world had been that fast. Across 8 competitions since December 2023, she has put 172 official solves on the record across four events. Solve to solve, her 3×3 times vary about 12% around a typical one, steadier than 72% of the 35,811 competitors with ten or more counted rounds. Her 3×3 best has come down from 16.41 in December 2023 to 9.58, a 42% improvement. Jingyi has entered eight competitions, more competitions than 90% of everyone who has ever competed.

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
