Long Zhou (周龙)
2×2 · top 4.7% of 186,767 all-time · competing since October 2017 · 2017ZHOU58
Long Zhou (周龙) has been competing for 9 years. His best event is the 2×2: a personal-best single of 1.99, set at China Championship 2019, puts him in the top 4.7% of the 186,767 people who have ever been ranked in the event, and 641st in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 7 competitions since October 2017, he has put 137 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 12% around a typical one, an early reading from 9 counted rounds. That figure sets aside his 4 DNFs. Long has entered seven competitions, more competitions than 88% 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.
