Xinhai Shi (石鑫海) has been competing for 9 years. His best event is the 4×4: a personal-best single of 39.97, set at Ezhou Open 2019, puts him in the top 12.1% of the 83,917 people who have ever been ranked in the event, and 1,296th in China. Across 6 competitions since April 2017, he has put 126 official solves on the record across ten events. Solve to solve, his 3×3 times vary about 10% around a typical one, an early reading from 7 counted rounds. That figure sets aside his 6 DNFs. His 3×3 best has come down from 20.85 in April 2017 to 12.46, a 40% improvement. Xinhai 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.
