Ruichen Hao (郝睿宸)
2×2 · top 4.5% of 189,179 all-time · competing since October 2017 · 2017HAOR01
Ruichen Hao (郝睿宸) has been competing for 9 years. His best event is the 2×2: a personal-best single of 1.96, set at Hefei Summer 2019, puts him in the top 4.5% of the 189,179 people who have ever been ranked in the event, and 620th in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 8 competitions since October 2017, he has put 144 official solves on the record across three events. Solve to solve, his 3×3 times vary about 13% around a typical one; 53% of the 36,406 competitors with ten or more counted rounds hold a tighter spread. His 2×2 best has come down from 6.03 in May 2018 to 1.96, a 67% improvement. Ruichen has entered eight competitions, more competitions than 90% 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.
