Haokai Su (苏浩凯)

2×2 · top 13.4% of 186,767 all-time · competing since July 2017 · 2017SUHA01

Haokai Su (苏浩凯) has been competing for 9 years. His best event is the 2×2: a personal-best single of 2.93, set at Xiamen Open 2019, puts him in the top 13.4% of the 186,767 people who have ever been ranked in the event, and 2,096th in China. Across 5 competitions since July 2017, he has put 67 official solves on the record across four events. Solve to solve, his 3×3 times vary about 12% around a typical one, an early reading from 6 counted rounds. That figure sets aside his 4 DNFs. His 3×3 best has come down from 22.62 in July 2017 to 15.79, a 30% improvement. Haokai has entered five competitions, more competitions than 83% of everyone who has ever competed.

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.
