Xiaohan Sun (孙效涵)
Skewb · top 5.1% of 73,281 all-time · competing since March 2017 · 2017SUNX01
Xiaohan Sun (孙效涵) has been competing for 10 years. His best event is the Skewb: a personal-best single of 3.03, set at China Championship 2018, puts him in the top 5.1% of the 73,281 people who have ever been ranked in the event, and 282nd in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 8 competitions since March 2017, he has put 184 official solves on the record across six events. Solve to solve, his 3×3 times vary about 15% around a typical one; 88% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 17.74 in March 2017 to 12.89, a 27% improvement. Xiaohan 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.
