James Bui

Square-1 · top 5.0% of 25,272 all-time · competing since November 2019 · 2019BUIJ01

James Bui has been competing for 7 years. His best event is the Square-1: a personal-best single of 9.33, set at Cubing at The Cube Saturday 2023, puts him in the top 5.0% of the 25,272 people who have ever been ranked in the event, and 52nd in Australia. Until October 2010, no official Square-1 solve in the world had been that fast. Across 6 competitions since November 2019, he has put 103 official solves on the record across five events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 89% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 21.08 in November 2019 to 10.56, a 50% improvement. James has entered six competitions, more competitions than 86% of everyone who has ever competed.

The story so far

Competitions

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.
