Rusong Shi (石如淞)

4×4 · top 3.5% of 83,917 all-time · competing since March 2017 · 2017SHIR01

Rusong Shi (石如淞) has been competing for 10 years. His best event is the 4×4: a personal-best single of 31.09, set at SJTU Open 2018, puts him in the top 3.5% of the 83,917 people who have ever been ranked in the event, and 356th in China. Until May 2011, no official 4×4 solve in the world had been that fast. Across 6 competitions since March 2017, he has put 139 official solves on the record across six events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 97% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 19.42 in March 2017 to 11.53, a 41% improvement. Rusong has entered six competitions, more competitions than 86% 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.
