Guanlin Zhou

3×3 · top 0.91% of 284,439 all-time · competing since January 2019 · 2019ZHOU01

Guanlin Zhou has been competing for 8 years. His best event is the 3×3: a personal-best single of 6.57, set at Ajax 3x3x3 Morning 2023, puts him in the top 0.91% of the 284,439 people who have ever been ranked in the event, and 92nd in Canada. Until May 2011, no official 3×3 solve in the world had been that fast. Across 12 competitions since January 2019, he has put 247 official solves on the record across seven 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 3×3 best has come down from 15.65 in January 2019 to 6.57, a 58% improvement. Guanlin has entered twelve competitions, more competitions than 94% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
