Jianfeng Yu (余剑锋) has been competing for 16 years. His best event is the 3×3: a personal-best single of 9.73, set at Guangzhou Rubik's Cube Day 2013, puts him in the top 6.7% of the 284,439 people who have ever been ranked in the event, and 2,617th in China. Until November 2007, no official 3×3 solve in the world had been that fast. Across 4 competitions since August 2010, he has put 85 official solves on the record across four 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. His 3×3 best has come down from 11.90 in August 2010 to 9.73, an 18% improvement. Jianfeng has entered four competitions, more competitions than 78% 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.
