2×2 · top 0.95% of 186,767 all-time · competing since April 2019 · 2019JIAN23
Siqi Jiang (蒋偲祺) has been competing for 7 years. His best event is the 2×2: a personal-best single of 1.17, set at Xi'an Cherry Blossom 2026, puts him in the top 0.95% of the 186,767 people who have ever been ranked in the event, and 100th in China. Until November 2008, no official 2×2 solve in the world had been that fast. Across 6 competitions since April 2019, he has put 118 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 13.82 in April 2019 to 9.52, a 31% improvement. Siqi has entered six competitions, more competitions than 86% 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.
