Karl Zhao

3×3 · top 10.1% of 284,439 all-time · competing since February 2014 · 2014ZHAO01

Karl Zhao has been competing for 13 years. His best event is the 3×3: a personal-best single of 10.87, set at Rockville Winter 2017, puts him in the top 10.1% of the 284,439 people who have ever been ranked in the event, and 5,461st in the United States. Across 6 competitions since February 2014, he has put 88 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 94% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 3 DNFs. His 3×3 best has come down from 25.00 in February 2014 to 10.87, a 57% improvement. Karl has entered six competitions, more competitions than 86% 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.
