4×4 · top 1.1% of 83,917 all-time · competing since April 2017 · 2017SHEN09
Chew Yun Sheng has been competing for 9 years. His best event is the 4×4: a personal-best single of 26.32, set at Penang One Bigger 2025, puts him in the top 1.1% of the 83,917 people who have ever been ranked in the event, and 19th in Malaysia. Until June 2013, no official 4×4 solve in the world had been that fast. Across 8 competitions since April 2017, he has put 320 official solves on the record across ten events. Solve to solve, his 3×3 times vary about 13% around a typical one; 54% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 4 DNFs. His 3×3 best has come down from 12.88 in April 2017 to 7.27, a 44% improvement. Chew 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.
