Andrew Chai has been competing for 6 years. His best event is the Pyraminx: a personal-best single of 2.40, set at Melbourne Summer 2021, puts him in the top 1.9% of the 129,321 people who have ever been ranked in the event, and 96th in Australia. Until January 2011, no official Pyraminx solve in the world had been that fast. Across 7 competitions since January 2021, he has put 225 official solves on the record across six events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 68% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 15.28 in January 2021 to 10.51, a 31% improvement. Andrew 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.
