Kaigan Yu (俞凯淦)
Skewb · top 3.2% of 73,281 all-time · competing since May 2018 · 2018YUKA01
Kaigan Yu (俞凯淦) has been competing for 8 years. His best event is the Skewb: a personal-best single of 2.57, set at China Championship 2019, puts him in the top 3.2% of the 73,281 people who have ever been ranked in the event, and 168th in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 7 competitions since May 2018, he has put 241 official solves on the record across four events. Solve to solve, his 3×3 times vary about 14% around a typical one; 78% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 2×2 best has come down from 4.23 in May 2018 to 2.11, a 50% improvement. Kaigan has entered seven competitions, more competitions than 88% 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.
