Sihan Jiao (焦思涵)

3×3 · top 4.5% of 284,439 all-time · competing since August 2010 · 2010JIAO04

Sihan Jiao (焦思涵) has been competing for 16 years. His best event is the 3×3: a personal-best single of 8.86, set at Zibo Open 2017, puts him in the top 4.5% of the 284,439 people who have ever been ranked in the event, and 1,735th in China. Until May 2008, no official 3×3 solve in the world had been that fast. Across 18 competitions since August 2010, he has put 518 official solves on the record across four events. Solve to solve, his 3×3 times vary about 9% around a typical one, steadier than 99% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 14.80 in August 2010 to 8.86, a 40% improvement. Sihan has entered 18 competitions, more competitions than 96% 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.
