Sijian Zhao (赵思鉴)
Pyraminx · top 0.98% of 129,321 all-time · competing since April 2024 · 2024ZHAO18
Sijian Zhao (赵思鉴) has been competing for 2 years. His best event is the Pyraminx: a personal-best single of 1.90, set at Shenyang Autumn 2025, puts him in the top 0.98% of the 129,321 people who have ever been ranked in the event, and 108th in China. Until April 2012, no official Pyraminx solve in the world had been that fast. Across 8 competitions since April 2024, he has put 229 official solves on the record across five events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 70% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 4 DNFs. His Pyraminx best has come down from 8.30 in April 2024 to 1.90, a 77% improvement. Sijian has entered eight competitions, more competitions than 90% of everyone who has ever competed.

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.
