Jiehao Guo (郭家豪)
Skewb · top 7.8% of 73,281 all-time · competing since May 2017 · 2017GUOJ05
Jiehao Guo (郭家豪) has been competing for 9 years. His best event is the Skewb: a personal-best single of 3.50, set at Xi'an 10th Anniversary 2019, puts him in the top 7.8% of the 73,281 people who have ever been ranked in the event, and 444th in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 4 competitions since May 2017, he has put 144 official solves on the record across ten events. Solve to solve, his 3×3 times vary about 25% around a typical one, an early reading from 6 counted rounds. That figure sets aside his 2 DNFs. His 2×2 best has come down from 6.97 in May 2017 to 3.80, a 45% improvement. Jiehao 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.
