Zhi Geng (耿智) has been competing for 13 years. His best event is the Skewb: a personal-best single of 3.49, set at Xi'an Cherry Blossom 2015, puts him in the top 7.7% of the 73,281 people who have ever been ranked in the event, and 439th in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 11 competitions since December 2013, he has put 384 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 15% around a typical one; 81% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 2×2 best has come down from 6.51 in December 2013 to 2.52, a 61% improvement. Zhi 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.
