Lincheng Cai (蔡林成) has been competing for 13 years. His best event is the Pyraminx: a personal-best single of 2.17, set at Yangjiang Open 2019, puts him in the top 1.4% of the 129,321 people who have ever been ranked in the event, and 157th in China. Until July 2011, no official Pyraminx solve in the world had been that fast. Across 73 competitions since January 2014, he has put 2,323 official solves on the record across 13 events. Solve to solve, his 3×3 times vary about 13% around a typical one; 61% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 20.78 in January 2014 to 9.42, a 55% improvement. Lincheng has entered 73 competitions, more competitions than 99% 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.
