Rongjin Huang (黄荣进)

2×2 · top 3.3% of 186,767 all-time · competing since October 2009 · 2009HUAN17

Rongjin Huang (黄荣进) has been competing for 17 years. His best event is the 2×2: a personal-best single of 1.75, set at One-to-eight Cubes Competition 2011, puts him in the top 3.3% of the 186,767 people who have ever been ranked in the event, and 432nd in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 10 competitions since October 2009, he has put 306 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 9% around a typical one, steadier than 99% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 6 DNFs. His 3×3 best has come down from 16.33 in October 2009 to 11.06, a 32% improvement. Rongjin has entered ten competitions, more competitions than 92% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
