Rong Zeng (曾嵘)
3×3 · top 7.2% of 284,439 all-time · competing since October 2009 · 2009ZENG07
Rong Zeng (曾嵘) has been competing for 17 years. His best event is the 3×3: a personal-best single of 9.91, set at Guangzhou SCAU 2012, puts him in the top 7.2% of the 284,439 people who have ever been ranked in the event, and 2,809th in China. Until May 2007, no official 3×3 solve in the world had been that fast. Across 11 competitions since October 2009, he has put 216 official solves on the record across six events. Solve to solve, his 3×3 times vary about 9% around a typical one, steadier than 99% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 4 DNFs. His 3×3 best has come down from 13.28 in October 2009 to 9.91, a 25% improvement. Rong has entered eleven competitions, more competitions than 93% 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.
