Zicong Weng (翁子聪) has been competing for 12 years. His best event is the Pyraminx: a personal-best single of 3.02, set at Yangjiang Open 2019, puts him in the top 3.7% of the 129,321 people who have ever been ranked in the event, and 447th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 57 competitions since October 2014, he has put 1,070 official solves on the record across ten events. Solve to solve, his 3×3 times vary about 15% around a typical one; 83% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 52.65 in October 2014 to 10.52, an 80% improvement. Zicong has entered 57 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.
