Skewb · top 6.0% of 73,281 all-time · competing since March 2024 · 2024SUNJ01
Jiaren Sun (孙嘉仁) has been competing for 2 years. His best event is the Skewb: a personal-best single of 3.19, set at Deqing Small & Special 2026, puts him in the top 6.0% of the 73,281 people who have ever been ranked in the event, and 25th in Hong Kong, China. Until February 2014, no official Skewb solve in the world had been that fast. Across 9 competitions since March 2024, he has put 148 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 11% around a typical one, an early reading from 9 counted rounds. That figure sets aside his 3 DNFs. His Skewb best has come down from 4.92 in April 2024 to 3.19, a 35% improvement. Jiaren has entered nine competitions, more competitions than 91% 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.
