Pyraminx · top 3.9% of 129,321 all-time · competing since February 2013 · 2013XUAN01
Chia Bing Xuan has been competing for 14 years. His best event is the Pyraminx: a personal-best single of 3.07, set at Singapore AMK CC Cubing A 2023, puts him in the top 3.9% of the 129,321 people who have ever been ranked in the event, and 47th in Singapore. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 10 competitions since February 2013, he has put 193 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 85% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 20.63 in February 2013 to 9.66, a 53% improvement. Chia has entered ten competitions, more competitions than 92% 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.
