Jianrong Chen (陈健荣) has been competing for 9 years. His best event is the Megaminx: a personal-best single of 46.65, set at Shenyang Open 2023, puts him in the top 3.7% of the 34,786 people who have ever been ranked in the event, and 80th in China. Until April 2011, no official Megaminx solve in the world had been that fast. Across 6 competitions since November 2017, he has put 174 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 14% around a typical one; 68% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 11.48 in November 2017 to 9.64, a 16% improvement. Jianrong has entered six competitions, more competitions than 86% 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.
