Kuan Kai Zac (官楷哲) has been competing for 3 years. His best event is the Pyraminx: a personal-best single of 3.48, set at Malaysia Cube Championship 2023, puts him in the top 5.4% of the 129,321 people who have ever been ranked in the event, and 98th in Malaysia. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 7 competitions since May 2023, he has put 90 official solves on the record across three events. Solve to solve, his 3×3 times vary about 13% around a typical one, an early reading from 8 counted rounds. His 3×3 best has come down from 19.53 in May 2023 to 12.94, a 34% improvement. Kuan has entered seven competitions, more competitions than 88% 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.
