Hui Hing Ngai (許慶毅)
4×4 · top 2.0% of 83,917 all-time · competing since August 2015 · 2015NGAI01
Hui Hing Ngai (許慶毅) has been competing for 11 years. His best event is the 4×4: a personal-best single of 28.45, set at Stevenage September 2025, puts him in the top 2.0% of the 83,917 people who have ever been ranked in the event, and 15th in Hong Kong, China. Until April 2012, no official 4×4 solve in the world had been that fast. Across 3 competitions since August 2015, he has put 57 official solves on the record across five events. Solve to solve, his 3×3 times vary about 12% around a typical one, an early reading from 6 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 22.44 in August 2015 to 8.68, a 61% improvement. Hui has entered three competitions, more competitions than 69% 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.
