Jianghao Chen (陈江浩)

Pyraminx · top 8.0% of 129,321 all-time · competing since July 2017 · 2017CHEJ02

Jianghao Chen (陈江浩) has been competing for 9 years. His best event is the Pyraminx: a personal-best single of 4.07, set at Longyan Open 2019, puts him in the top 8.0% of the 129,321 people who have ever been ranked in the event, and 953rd in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 5 competitions since July 2017, he has put 166 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 14% around a typical one, an early reading from 8 counted rounds. That figure sets aside his 2 DNFs. His Pyraminx best has come down from 6.95 in July 2017 to 4.07, a 41% improvement. Jianghao 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.
