Song-Fan Cai (蔡松汎) has been competing for 8 years. His best event is the 3×3: a personal-best single of 10.65, set at Kaohsiung Autumn Open 2019, puts him in the top 9.4% of the 284,439 people who have ever been ranked in the event, and 567th in Chinese Taipei. Until August 2006, no official 3×3 solve in the world had been that fast. Across 6 competitions since March 2018, he has put 152 official solves on the record across five events.

His 3×3 best has come down from 21.35 in March 2018 to 10.65, a 50% improvement. He has entered six competitions, more competitions than 86% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
