Hewson Kang Poh Jun (江博俊) has been competing for 4 years. His best event is the Pyraminx: a personal-best single of 1.09, set at USM Penang Cube 2025, puts him in the top 0.072% of the 129,321 people who have ever been ranked in the event, and 3rd in Malaysia. Until June 2018, no official Pyraminx solve in the world had been that fast. Across 12 competitions since December 2022, he has put 385 official solves on the record across four events. Solve to solve, his 3×3 times vary about 15% around a typical one; 80% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 9.16 in December 2022 to 7.17, a 22% improvement. Hewson has entered twelve competitions, more competitions than 94% 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.
