Wantong Chi (迟婉彤) has been competing for 10 months. Her best event is the 2×2: a personal-best single of 2.16, set at Hefei Open 2025, puts her in the top 5.9% of the 186,767 people who have ever been ranked in the event, and 831st in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 4 competitions since October 2025, she has put 35 official solves on the record across two events. Solve to solve, her 3×3 times vary about 12% around a typical one, an early reading from 6 counted rounds. Her 3×3 best has come down from 16.00 in October 2025 to 10.23, a 36% improvement. Wantong has entered four competitions, more competitions than 78% 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.
