Pyraminx · top 30.0% of 129,321 all-time · competing since November 2024 · 2024SUNS02
Shou-ching Sun has been competing for a year. His best event is the Pyraminx: a personal-best single of 7.26, set at Davis Spring 2025, puts him in the top 30.0% of the 129,321 people who have ever been ranked in the event, and 417th in Chinese Taipei. Across 5 competitions since November 2024, he has put 50 official solves on the record across three 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 4 DNFs. His 3×3 best has come down from 31.02 in November 2024 to 20.38, a 34% improvement. He has entered five competitions, more competitions than 83% of everyone who has ever competed.

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.
