Clock · top 2.5% of 32,048 all-time · competing since May 2025 · 2025SHIH04
Julia Shi has been competing for a year. Her best event is the Clock: a personal-best single of 4.09, set at Bay Area Speedcubin' 68 - Belmont 2025, puts her in the top 2.5% of the 32,048 people who have ever been ranked in the event, and 44th in China. Until June 2015, no official Clock solve in the world had been that fast. Across 3 competitions since May 2025, she has put 61 official solves on the record across five events. Solve to solve, her 3×3 times vary about 12% around a typical one, an early reading from 5 counted rounds. Her 3×3 best has come down from 24.78 in May 2025 to 16.19, a 35% improvement. Julia has entered three competitions, more competitions than 69% 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.
