Yoshiki Chinen (知念良樹)

3×3 · top 7.3% of 284,439 all-time · competing since February 2012 · 2012CHIN01

Yoshiki Chinen (知念良樹) has been competing for 15 years. His best event is the 3×3: a personal-best single of 9.94, set at Kyushu Open 2013, puts him in the top 7.3% of the 284,439 people who have ever been ranked in the event, and 320th in Japan. Until May 2007, no official 3×3 solve in the world had been that fast. Across 10 competitions since February 2012, he has put 167 official solves on the record across five events. Solve to solve, his 3×3 times vary about 14% around a typical one; 64% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 12.05 in February 2012 to 9.94, an 18% improvement. Yoshiki has entered ten competitions, more competitions than 92% of everyone who has ever competed.

The story so far

Competitions

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.
