Clock · top 3.3% of 32,048 all-time · competing since March 2025 · 2025LUXU01
Xu Zhong Lu (徐仲橹) has been competing for a year. Her best event is the Clock: a personal-best single of 4.48, set at Xianju Special 2026, puts her in the top 3.3% of the 32,048 people who have ever been ranked in the event, and 13th in Hong Kong, China. Until June 2015, no official Clock solve in the world had been that fast. Across 5 competitions since March 2025, she has put 46 official solves on the record across three events. Solve to solve, her 3×3 times vary about 15% around a typical one, an early reading from 7 counted rounds. Her 3×3 best has come down from 11.48 in March 2025 to 9.70, a 16% improvement. Xu has entered five competitions, more competitions than 83% 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.
