Tong Zhu (朱彤) has been competing for 15 years. His best event is the 3×3 blindfolded: a personal-best single of 42.39, set at Sydney Open 2019, puts him in the top 7.5% of the 12,178 people who have ever been ranked in the event, and 123rd in China. Until August 2009, no official 3×3 blindfolded solve in the world had been that fast. Across 20 competitions since July 2011, he has put 448 official solves on the record across ten events. Solve to solve, his 3×3 times vary about 14% around a typical one; 63% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 14.36 in July 2011 to 12.75, an 11% improvement. Tong has entered 20 competitions, more competitions than 97% 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.
