Yinzhi Sha (沙印志) has been competing for 7 years. His best event is the 4×4: a personal-best single of 21.58, set at Xuzhou Zenith 2026, puts him in the top 0.15% of the 83,917 people who have ever been ranked in the event, and 17th in China. Until October 2015, no official 4×4 solve in the world had been that fast. Across 17 competitions since July 2019, he has put 492 official solves on the record across six events. Solve to solve, his 3×3 times vary about 14% around a typical one; 70% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 4×4 best has come down from 36.61 in July 2019 to 21.58, a 41% improvement. Yinzhi has entered 17 competitions, more competitions than 96% 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.
