Chuansheng Lu (卢传盛)

2×2 · top 8.8% of 186,767 all-time · competing since August 2017 · 2017LUCH06

Chuansheng Lu (卢传盛) has been competing for 9 years. His best event is the 2×2: a personal-best single of 2.49, set at Dongguan Summer 2019, puts him in the top 8.8% of the 186,767 people who have ever been ranked in the event, and 1,300th in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 4 competitions since August 2017, he has put 135 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 12% around a typical one, an early reading from 5 counted rounds. That figure sets aside his 2 DNFs. His 2×2 best has come down from 4.35 in August 2017 to 2.49, a 43% improvement. Chuansheng has entered four competitions, more competitions than 78% of everyone who has ever competed.

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.
