4×4 · top 2.4% of 83,917 all-time · competing since July 2011 · 2011CHEN29

Zelin Chen (陈泽霖) has been competing for 15 years. His best event is the 4×4: a personal-best single of 29.31, set at Asian Championship 2016, puts him in the top 2.4% of the 83,917 people who have ever been ranked in the event, and 231st in China. Until April 2012, no official 4×4 solve in the world had been that fast. Across 8 competitions since July 2011, he has put 261 official solves on the record across six events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 88% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 18.00 in July 2011 to 9.13, a 49% improvement. Zelin has entered eight competitions, more competitions than 90% 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.
