Liudi Sun (孙柳笛) has been competing for 14 years. Her best event is the 2×2: a personal-best single of 2.10, set at Hangzhou Open 2018, puts her in the top 5.4% of the 186,767 people who have ever been ranked in the event, and 758th in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 42 competitions since November 2012, she has put 1,483 official solves on the record across 17 events.

Her 3×3 best has come down from 26.75 in November 2012 to 10.28, a 62% improvement. Liudi has entered 42 competitions, more competitions than 99% 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.
