Rongson Li Chen

2×2 · top 0.5% of 186,767 all-time · competing since February 2019 · 2019CHEN16

Rongson Li Chen has been competing for 8 years. His best event is the 2×2: a personal-best single of 0.97, set at Bolton Spring 2023, puts him in the top 0.5% of the 186,767 people who have ever been ranked in the event, and 43rd in the United Kingdom. Until November 2008, no official 2×2 solve in the world had been that fast. Across 7 competitions since February 2019, he has put 192 official solves on the record across six events. Solve to solve, his 3×3 times vary about 14% around a typical one; 71% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 2×2 best has come down from 3.85 in February 2019 to 0.97, a 75% improvement. Rongson has entered seven competitions, more competitions than 88% 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.
